The Hobbit | Summary and Analysis

The Hobbit Summary and AnalysisThe Hobbit is an exciting conjuring trick ab expose a hobbit that goes on the most godforsaken adventure of his life. Bilbo (hobbit) goes to Middle Earth to seek the long lost treasure. Along the way, Bilbo encounters new friends, strange wild beasts, unlimited amount of danger, and temptation. The plot of this magnificent envisage fits the quest pattern from the beginning, each the way to the end. The founts contained within the words of this novel fir the archetypal characters in every way. IN addition, the settings of this particular adventure lay down some occasion supernatural and enchanted ab off them. These atomic number 18 the elements required to having the correct quest, and The Hobbit contains all these elements. in that respectfore, The Hobbit is a very good example of a monomyth.The plot of this book contains one-third distinct phases departure, initiation, and return. The departure phase often contains the call to adventure, t he refusal, a supernatural aid, and crossing the first threshold. The call to adventure in this novel occurs when one day, Gandalf appears and asks Bilbo to go on an adventure with him in the following manner Im looking for someone to share in an adventure that Im arranging p.6. There is also a refusal of the call, We are plain quiet folk, and rich person no use for adventures p.6. The supernatural aid is Gandalf, the wise old wizard, and when the dwarves and Bilbo encounter the trolls, p.34-41 Gandalf take places and helps them and saves them all, and the first threshold is crossed. Bilbo and the dwarves eject now move on. After the departure, Bilbo and the dwarves undertake an initiation, and are captured many a nonher(prenominal) times and almost killed if it were not for Bilbo. In the road of trials, Bilbo and the dwarves face many dangers and Bilbo has to save his friends many times later on they are captured, and through this, he gains a great deal of wisdom and is raise d to a higher status when he saves them from the wood-elves prison p.166-175. Ultimately, when it is time to go back, Bilbo is hesitant to return because he has made so many new friends and is sooner fond of them, but soon, he leaves with the elves, Beorn, and Gandalf with two trunks full of luxurious and silver as the boon and continues to lead a simple life. He is now the master of two worlds, and he can go back anytime he wants without any fear. Thus, the plot of The Hobbit fits the monomyth.The characters in The Hobbit fit the archetypal characters of the monomyth pattern. For example, there is a hero (Bilbo) the wise, old man (Gandalf) and the condemnable villains (the goblins, the Wargs, the wood-elves, the trolls, Gollum, Smaug, and Bolg). In a typical quest, readers forestall to find evil characters that must be outwitted or defeated by the hero. In this case, it is the goblins, the Wargs etc. Bilbo is expected to defeat, who will not stop at anything to cop their hands on the treasure, even if it means killing millions. Bilbo defeats Gollum in the riddle contest and when Gollum decided to kill Bilbo, Bilbo uses the magic ring to become invisible and follows Gollum out of the caves p.70-84. Next, the goblins capture the adventurers and after the escape of Bilbo and his friends, the goblins join armies with the Wargs and are ready to cremate them when the Eagles come and save the dwarves, the wizard and Bilbo p.99-100. The trolls that catch the dwarves in sacks, are ready to bang them and ear them when Gandalf appears uses his brain and saves them all p.37-42. When the travellers are captured by the goblins, Gandalf disappears from his spot and later appears in the tunnel, kills the Great Goblin, and helps the dwarves and Bilbo escape p.57-63. Smaug, the dragon and the guardian of the treasure, is killed by Bard out front the war with the help of a thrush p.231-232. However, Bolg (son of the Great Goblin) is defeated by Beorn, the man who can tur n into a bear p.266-267. The one villain who dies without being killed is the outgo of the Town. He runs away with the treasure that is to be used to repair the town damaged by Smaug, and is later found dead with the treasure. Consequently, the characters in The Hobbit reflect the stately characters what would be found within any monomyth.The setting for The Hobbit is the Hill, Hobbiton, Rivendell, Misty Mountains, The Island of Gollum, Mirkwood, the prison of the Wood-Elves, The Lonely Mountain, Long Lake, and Esgaroth. The novel begins on the Hill, near Hobbiton and quickly moves to a magical place called Rivendell where the dwarves and Bilbo stay for a while to get fresh supplies. Soon, they leave Rivendell and enter the dangerous Misty Mountains where they are captured by the goblins p.57-63. After they have all escaped into the tunnels, Bilbo falls on the way, finds Gollum on his Island, and scarcely escapes from him and the goblin army p.65-84. Next, the dwarves, Bilbo and G andalf go to the house of Beorn, who lives near the forest of Mirkwood p.108-111. Later, they enter the forest of Mirkwood p.128-132, and have many more adventures. Then they see the light coming from the bushes and go off path (as they were told not to do) and are captured by giant spiders. After being released, they reach that Thorin, their leader, has been captured by the wood-elves and to save him, they go after him and are prisoners of the wood-elves p.156-158. To escape, they have to journey through Long Lake in barrels p.170-180 and everything is done by Bilbo because he was not caught since he was invisible. Esgaroth is the last town in the first place the Lonely Mountains and their second last stop as well 182-187. The last stop for the dwarves is their destination, The Lonely Mountain, for which they have come all the way. The are much wiser than when they started out, and they are very delighted to be at their destination, but they have one last barrier, the dragon, to conquer before they can claim the riches. The setting insists that the reader use their imagination, illuminating images of what unmarked worlds might be like when man has dominated his most despised rival. Therefore, the setting of The Hobbit is suitably impressive in degree and fits the form of an ambitious and heroic quest across the universe.The Hobbit is a very good example of a monomyth because the elements required to having the perfect quest are contained within The Hobbit. The plot of this glorious ideate fits the quest pattern from the start, all the way to the conclusion. The characters enclosed with the words of this novel fit the precedent characters in every way. Additionally, the settings of this particular journey have something miraculous and charming about them. Along the way, Bilbo encountered new friends, wild beasts, heaps of danger, and temptation and gained wisdom from his experiences. Bilbo started out to seek the long lost treasure, and found out what the real treasures were friendship, honesty, and trust. The Hobbit is a thrilling magic about a hobbit that goes on the most dangerous pilgrimage of his life.About the ways in which The Hobbit demonstrates the features of the partiality genre.The Hobbit is a fantasy novel about a peaceful hobbit that accompanies a wizard and several dwarves on a journey to steal the great treasures of the dragon Smaug and I believe it demonstrates or uses the features of the fantasy genre. The features of any genre are like a skeleton for the paper of that particular genre. Different genres have different features such as different settings, characters, plot, themes and value. Features are like a list of criteria that is used to assess whether the novel fits into a genre. The Hobbit is unable to demonstrate the entire features of the fantasy genre but it is still clear that The Hobbit used the features of the fantasy genre as a skeleton.The first thing to consider when determining whether The Hobbi t demonstrates the features of the fantasy genre is the setting. The setting is the where the story takes place. Most fantasy stories take place an enclosed world that is often foreign and inexplicable (Glasson, 1955, p.55). The setting in The Hobbit follows this idea and the world that it takes place is enclosed and exotic. With rows of strange and devious mountains and thick woods where elves and giant spiders live The Hobbit world is definitely exotic with the abundance of several other creatures and dragons the world of The Hobbit is also quite mystical and magical. The setting of any genre is the fundamental building block for a stories development. For example, it is quite hard to create an interesting science fiction story that is set in the backyard of a young boy. The Hobbit proves that it uses the writing structure of the fantasy genre by being set in a magical land full of exotic creatures and landforms which are the elements of a typical fantasy story. Setting isnt the only looking at to be considered when writing a fantasy story there are also characters to be put into consideration. In the fantasy genre there are usually the friend and the antagonist that are in conflict with each other. In The Hobbit the protagonist is a simple hobbit, known as Bilbo Baggins, who becomes a despoiler on a plan to steal treasures. There is no antagonist in The Hobbit. Smaug is not the antagonist because an antagonist is a principal character that opposes the protagonist (www.thefreedictionary.com). Throughout the book Smaug does not oppose Bilbo Baggins until he is provoked. He is more of an obstacle than a villain opposing Bilbo and his party of dwarves.On the other hand, The Hobbit demonstrates the features of the fantasy genre through the development of Bilbo. Protagonists in fantasy stories are well-known for their development or alternate. For example, in the book called Eragon the main character transforms from a deer hunting farm boy into a fierce and powerful dragon rider. In the beginning of the book Bilbo defines himself and the hobbits as Plain quiet folk and have no use for adventure (The Hobbit, p.4). Throughout the book Bilbo changes into an extroverted and adventure-seeking hobbit through his experiences. Bilbo had changed from a simple hobbit into a fantasy protagonist with that could fulfil the task at hand. Most stories have a diverse range of characters and within these characters are the protagonist and antagonist. Different genres have different personalities or criteria for their main characters. The main character in a fantasy story is usually changing, confident and adventurous. The evidence clearly reveals that The Hobbit demonstrates the features of the fantasy through the knowledge or skills that the hero gains through his quest.secret plan and structure is a key feature to the features of the fantasy genre. The plot and structure in the fantasy is quite unique in contrast to the features of other genres. The re is calm, upheaval, calm then stability is restored (Glasson, 1955, p. 55) shows the dynamic structure of a fantasy quest. The Hobbit starts off in a peaceful and calm atmosphere until Bilbo joins Gandalf and the fourteen dwarves in an adventure. During his journey the calm atmosphere is break and upheaved. When the journey ends Bilbo goes back to his normal life, despite his grown love for adventure. Stability is restored at the end of The Hobbit because the arrogant dragon was killed and Bilbos returning to his peaceful life after a crazy adventure.The plot in a fantasy story usually centres on the heros quest or journey. The quest is usually a search for a powerful or ancient object that will restore the stability or calm that was disrupted by evil. The Hobbit conforms to this by foc employ on Bilbos journey but the object (treasure) doesnt restore the calm but instead creates conflict. In The Hobbit Thorin and his cousin nearly take hold war but are forced to join in an atte mpt to stop the Goblin army. With this evidence it is obvious that the quest was not aimed to destroy evil and it even started conflict. The quest in The Hobbit strays from the criteria of a typical fantasy story.Every protagonist in any genre encounters obstacles throughout story but the reasons for these obstacles change depending on the genre. A dramatic story would use obstacles as a method to exemplify the feeling of the character or his/her flaws while a fantasy story would use obstacles as a test for to prove the character is worthy or expedient. For example, Bilbo encounters three trolls and tries to pickpocket an object from one of the trolls but he is discovered and captured in his attempt. This obstacle couldve been made to show that Bilbo is not yet a master of stealing and how he still needs to improve before his convergence with Smaug. Most of the elements in The Hobbit successfully combine to create a suitable plot and structure for a fantasy novel.The Hobbit doesnt c ompletely demonstrate the features of a fantasy story mainly due to the themes and values in the story. In a fantasy quest Tradition values are fought for (Glasson, 1955, p. 55). Throughout The Hobbit values are not fought for. For example, Bilbo believed in a simple and harmonious life that is adventure free but as he doesnt fight for what he believes in and ends up accepting Gandalfs request. Even when delving deeper into the story values are not fought for and some are even broken. There are different opinions on the features of the fantasy genre and how a book fits into a particular genre and it makes it hard to find out whether a book really uses the features as an outline. By using the typical opinion of the criteria or features of a fantasy quest it is quite clear that The Hobbit follows these outlines. The Hobbit is able to include an enclosed and exotic setting, mystical creatures, characters that learn from their mistakes and flaws, a plot that focuses on a quest for an ob ject and obstacles that test and teach the hero during his quest. Even though The Hobbit doesnt use the themes and values of a typical fantasy quest but it still utilizes the features of the fantasy genre

Holes By Louis Sachar: Character Analysis

The plot of the novel is about the life of multiple characters and a leading character with whom the whole story of the novel is linked. Story is written in main two separate referring as flashback and current or present situation.Characters in the StoryThe major characters in the novel are Stanley Yelnats and Zero (Hector Zeroni). Present characters are Stanley Yelnats, Mrs. Bell, Stanley Yelnats III, BarfBag, Alan, Theodore, Jos, Ricky, Twitch, Attorney General, Ms. Morengo, Clyde confection Feet Livingston and Mr. Sir. Other past characters are Elya Yelnats, Madame Zeroni, Stanley Yelnats II, Kate Barlow, Myra Menke, Igor Barkov, Charles Trout Walker, surface-to-air missile, the Onion Man, Mary Lou and Sheriff.Brief Overview to StoryThe storyline is the story occurred in past along the present storyline. Stanley is an luckless junior boy because his family had been cursed for many ages before his great-great grandfather had not kept his promise. Stanleys father was a failure inventor and after inventing something using waste tennis ball. Financially Stanleys family was poor and believes that it is the result of the curse that his family has been bearing for ages. On the former(a) side there is another story of Kate Barlow who is an intelligent lady and teaches in unrivaled class room school. She used to savour Sam the onion boy who a black guy. The towns people were racist and did not like Kate in love with a black man to whom Kate love because he was a nice man. One day Sam was killed after Kate kisses him and the shoemakers last of Sam makes Kate furious that she decides to eat up revenge of Sams death. Stanleys great-great grandfather Stanley I, who had not kept his promise, migrate to America and earn money but he was robbed by Kate Barlow and after that Stanleys family consistently facing pecuniary crises. In pre sent situation Stanleys was falsely accused of theft and trialed. At the end of the trial he was asked to choose either going jailhouse or Green Lake pack. Since Stanley has ever thought it as some kind of summer camp he chooses going Green Lake Camp. Having reached the camp it was revealed on him that the Green Lake Camp is not in any way like summer camp and on the contrary it is rather a excavation camp. Here Stanley somehow adjusted and began to part in the digging. He also makes booster stations here like Zero (Hector Zeroni). One day Stanley finds that the warden is after something as she was keenly interested in digging. Stanley with his friend Zero finds the treasure which after known as his grandfathers lost treasure and he becomes legal owner of the treasure. All of sudden Stanleys fate turns in to his favor and his father finds the formula for removing feet stink and Clyde Sweet Feet become its primary endorser. Zero has confesses that he stole the shoes I actual, just because he lived by himself and was restrict steal to survive. The sudden change in fate stems from the reality that Zero was actually Hector Zeroni, and was the great-great grandson of Madame Zeroni. The promise was eventually been kept. A Yelnats lifted a Zeroni up to the mountain, carrying the curse and changing his familys fate.Comparison of Stanley Yelnats IV and Kate Barlows LivesKate Barlow was a humble, kind and intelligent lady. Nobody has thought that this kind lady will turn to become vindictive person and will cause the destruction and unhappiness of someone life. Kate Barlow was a teacher and teaches in a one-room school in Green Lake one snow and ten years before it was made Camp Green Lake. She was in love with a guy Sam he sells onions in the town. Kate loves him because he was compassionate, brave, and elegant. Sam was a black man and the people of town were racist and did not like when they know that she loves Sam. Though Kate was a white herself yet she wa s not racist and believes in good and nobility. Kate was very lucky here to find a true love in her life and it was her the luckiest moments when she knows that she is in love with Sam. But the death of Sam was revealed as disastrous for her and it was the most unlucky moment of her life because the death of Sam turns her life into another direction. Death of Sam makes her revengeful and later she lived a pathetic life. She later on robs Stanleys great-great grandfather and thus Kate Barlow and Stanley Yelnatss family get connected into chain of life.Stanley Yelnats, who was an ugly as he was three times heavier than other normal boys and poor young boy, was great-great grandson of Stanley I who was robbed by Kate Barlow. Stanleys family had been poor and suffering from financial crises since his great-great grandfather was robbed by Kate Barlow. Stanleys family has another tragedy in their life as his family was cursed due to miscommitment of his great-great grandfather with Madame Zeroni. The great-great grandfather of Stanley was in love with Elya Yelnats and wishes to marry her but her father had conditioned her marriage with the big pig. To him, he will award the marriage of his daughter with the man who brings the biggest pig. Madame Zeroni helped the great-great grandfather of Stanley on the condition to take her up on the mountain to drink stream water. Her condition to take her up on the mountain was so intense that she would curse him and his generation if he had not taken her up for helping him. Due to some reason he could not manage to bring her up on the mountain and they migrated to America. Here he was robbed by Kate Barlow and after that he thinks that he got Madame Zeronis curse. Due to this event Stanley and his family always think in the same manner and believe that they are unlucky and cursed. However, macrocosm accused of theft which was false and he had not committed the disgust was fiercely unlucky of him because he was punished for t he crime which he had never committed. At the end of the trial when he was asked to choose to go either to jail or Green Lake Camp, he chose to go to Green Lake Camp because he had always dreamed of summer camps and thought it one of them. But it was very unfortunate of him when he reaches at the camp and sees that there was neither a lake nor it was green and that his decision of coming here was wrong. Apparently feels himself unlucky because there was so overmuch hardworking involve in the camp. Boys were here to dig for building their characters. He had not realized that destiny intends to change his life and make him lucky. He began to digging here and one day he realized that the warden is after some treasure. He eventually finds the treasure and got released from camp as a result of being proved that he is innocent. The treasure that he found later came to know that it was the same value which Kate Barlow has robbed from his great-great grandfather and buried it here. Fortune was so much in his favor that his fathers formula also works and it was successful.

Explaining The Pumping Action In A Heart Physical Education Essay

Explaining The Pumping Action In A Heart Physical Education EssayThe cheek is the most important organ of the birth which keeps the opposite internal organs alive by supplying crease and oxygen thereof making it a life maintaining organ. The objective of this adjudicate is to explain the coreing per crapance of the heart, transportation of oxygen by the cardiovascular outline and how trim down demarcation flow can affect cardiac function. A treatment for this cardiac misfunction is also explained. I will begin the essay by explaining the anatomical structure of the heart and then explain how the pumping action of the heart. The second fracture of the essay will include how the reduction in blood flow can affect the cardiac function and finally a treatment to cure this paradox will be explained.The heart is a life maintaining organ weighs almost less then a pound, bargonly the size of the fist and located in the mediastinum of the throracic cavity of human body. The shap e of the heart is like a inverted cone which has a blunt tapered end that points to the left hip and the beastly pointing towards the pay off shoulder. The heart lies more close to the left that is nearly third of it and rest on the diaphragm in between the two lungs. This is shown in turn 1 which shows the location of the heart.Fig.1 Anterior view of the heart in the mediastinumThe entire heart is covered by a dense fibrous tissue called the pericardium which comprises of a dense connective tissue called the fibrous pericardium which protects the heart from over stretching receivable to excessive filling, it also consists of the serous pericardium which forms deeper portion of the heart. The serous layer is get ahead divided into the parietal layer which lines the outer layers the and visceral layer which lines the innermost layers of the heart. A fluid which reduces friction is present in the pericardial cavity that separates these parietal and visceral layers. The below tok en (see fig. 2 ) shows the different layers of the the pericardium.Fig.2 The pericardium and the Heart wallhttp//www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=cardiopart=A1016rendertype=figureid=A1019As shown in the above figure (see fig.2), the heart wall is undisturbed of three different layers epicardium, myocardium and the endocardium. The epicardium which forms superficial layer of the heart wall consists of mainly adipose tissue. The endocardium forms the deeper layer of the heart and is filled with squamous endothelium and aerolar tissues. Between these two layers lies the myocardium which is make up of cardiac muscles that help in the abridgement of the heart. Its relatively a thick layer as it helps the heart to perform its normal pumping action that is contraction and expansion of the heart at regular intervals. On the outer surface of the heart there many grooves and layers of fat called the sulci.The heart is divided into four house which has two inferior intermittent pumps which discharge blood out of the heart called the right and the left heart ventricles and two superior primer pumps called the right and left atria receiving deoxygenated and oxygenated blood from the body and the lungs respectively. The ventricles are separated from each new(prenominal) by a relatively thick muscle called the interventricular septum but atria are separated from each other by relatively a thinner wall called the interatrial septum as it has lighter workload analyze the ventricles. The right ventricle has thicker walls comparing the left ventricle because it has to pump more blood during arrangingic circulation. The presence of heart valves prevents the back flow blood and hence ensures that blood flows effectively in one direction. There are two types of valves which are the atrioventricular (AV) valves and the semilunar valves. The AV valves consists of the the angulate and bicuspid (mitral) valves that are located on the right and left side of the heart between the ventricles and atria respectively. The semilunar valves on the other hand lie on the bases of aorta and the pneumonic arterial blood vessel. These valves consists of the pulmonary valve and the aortic valve. The tricuspid valve has thread like structures that are connected to heftiness like cords called the chordae tendinae. The anatomical structure of the heart and the heart valves is shown in figure 3.Fig.3 The heart and the heart valveshttp//yoursurgery.com/ProcedureDetails.cfm?BR=3Proc=24Blood Flow by means of The HeartThe blood flow through the heart is explained by the pulmonary and systemic circulation. Deoxygenated blood is drained into the right atrium by the superior and the inferior vena cava. The pressure in the right atrium increases forcing the tricuspid valve to open and hence draining the entire deoxygenated blood to the right ventricle. The volume of blood in the ventricle increases and the maximal volume of the blood in the right ventricle after the contraction of the right atrium is called end diastolic volume (EDV). EDV is generally about 140ml. As the tricuspid valve closes the pressure in the ventricles increases. During this phase the ventricles contract but the pressure is not enough for the pulmonary valve to open hence resulting in isometric contraction as a result all the heart valves are closed during this phase and the volume in the ventricles remains constant. As the pressure continues to increase comparing the right atrium the blood forces open the pulmonary valve and the deoxygenated blood is pushed into the pulmonary trunk that divides into the pulmonary arteries. After the contraction of the ventricle that is the systole, the amount of blood remaining in the ventricle is called the end systolic volume (ESV). The difference between EDV and ESV gives the stroke volume (SV) that is the blood pumped out of the ventricles during a single heart beat. The pulmonary arteries carries the deoxygenated blood to the right and the left lung for oxygenation. Once the blood is oxygenated it is returned back to the heart by the pulmonary vein. The pulmonary vein empties the oxygenated blood into the left atrium, hence completing the pulmonary circulation and as the pressure in this atrium increases the blood is drained into the left ventricle by forcing open the mitral valve. When the mitral valve is closed the the pressure rises again comparing the left atrium and the blood is pushed into the aorta by opening the aortic valve. This oxygenated blood is transported to various parts of the body to carry out haemodynamic activities ( which includes the exchange of oxygen and carbondioxide with the blood ) . The systemic circulation is completed once the deoxygenated blood is returned back to the right atrium from different parts of the body by the venae caveae.Fig.4 Pulmonary and Systemic Circulation of the hearthttp//academic.kellogg.cc.mi.us/herbrandsonc/bio201_McKinley/f22-1_cardiovascular_sy_c.jpgDuring the phase of the first diastole, the ventricular relaxation takes place as a result the semilunar valves are closed and also the AV valves are also closed during this time as a result the volume of blood in the ventricles remains constant, hence this phase is called the isovolumetric relaxation. The diagrammatic explanation of the cardiac cycle is explained in figure 5.Fig.5 The cardiac Cyclehttp//academic.kellogg.cc.mi.us/herbrandsonc/bio201_McKinley/f22-11_cardiac_cycle_c.jpgCardiac Conduction SystemIn this system the pumping action of the heart is synchronised by the electrical activity of the heart. Electrical signals are generated by the sinoatrial (SA) pommel which is the bodies natural pacemaker. This node generates pulses that propagate throughout the right atrium and through the Bachmanns bundle hence stimulating both the atria. These pulses travel from SA node the to the atrioventricular (AV) node through certain paths known as internodal tracts. The AV node acts as a g atekeeper and prevents all the pulses to travel from the atria to the ventricles, hence causing some arrest in the excitation. From the AV node the signals travel through the Purkinje fibres that divides itself into right and left and excites both the ventricles. This process repeats and the contraction of the heart takes place.Transportation of oxygen by cardiovascular SystemThe cardiovascular system is a dense network of arteries, veins, capillaries etc. which is involved in the transportation of blood gases to and from the various parts of the body. In this part I will talking about how the cardiovascular system transports oxygen to different parts of the body. The oxygenated blood which is pumped from the left ventricle is transported by the aorta. The aorta is the largest arteria of the human body which is made up of several layers of the elastin fibers and covered by smooth muscle. Blood flows in the arteries with high pressures hence these arteries boom (vasodilation) and contract (vasoconstriction) so helping to regulate blood pressure. The aorta bifurcates into various different arteries smaller in size carrying oxygenated blood to different parts of the body. These arteries further divide into arterioles whose diameter is a good deal smaller comparing the arteries and are less elastic. These arterioles are made up of thick layer of smooth muscles and are controlled by the autonomic nervous system that control their diameter. Oxygenated blood now passes from the arterioles to the capillaries which are the functional unit of the cardiovascular system. Capillaries are responsible for the exchange of blood gases and other nutrients between different tissues and blood through the process of diffusion. As diffusion is the process by which gases or fluids flow from higher to lower concentration therefore at the capillary level the concentration of oxygen is more in the capillaries and on the other hand the concentration of carbondioxide is more in the tissue than in the capillaries therefore the diffusion of these gases takes place. Oxygen is diffused into the tissues and carbondioxide on the other hand is diffused into the tissues. This is how oxygen is transported to different parts of the body. This deoxygenated blood is collected from the venules which are connected to the capillaries. Theses venules group together to form veins. Hence this deoxygenated blood is returned back to the heart for oxygenation and the entire process is repeated. The entire process of the transportation of oxygen by the cardiovascular system is explained in figure 6Fig 6 Blood flow and capillary exchange of oxygenhttp//www.patient.co.uk/health/Blood-General-Overview.htmEffects Of Reduced Coronary Blood Flow And Its treatmentReduced coronary blood flow results in a condition known as ischemia where the myocardiac tissue is deprived of oxygen due to unequal blood flow. The inadequacy is caused by formation of localised plaques of lipids that protr ude within the artery causing a reduction in blood flow. As a result of reduced blood flow, there is a reduction in the level of oxygen which is required to carry out metabolic activities of the tissues. In ischemia the anaerobic respiration of the tissue results in the formation of lactic acid which leads to sever pain in the chest region. This pain is called angina pectoris. Angina pectoris is class into two types stable and unstable. Stable angina which causes pain in the chest region may arise from some physical activity ( running, jogging etc.). During these activities the use up for oxygen is more to carry out metabolic activities in a faster rate compared to the supply of oxygen as a result anaerobic respiration of the tissues takes place and hence results in the formation of lactic acids which causes this pain. In unstable angina there is a persistent pain in the chest regions this is because of the accumulation of platelets on the ruptured plaques which leads to the block age of the arteries and hence causing immense reduction in blood flow. Persistent unstable angina may cause myocardial infraction which ultimately may lead to sudden death. There are many ways to treat angina it may be either working(a) or non surgical ways. Surgical methods include coronary balloon angioplasty where a catheter is passed into an artery with a balloon at the tip of the catheter. The balloon is made to expand causing the artery to expand and hence breaking of the plaque of lipids in the artery. Another types of surgical method is the coronary bypass surgery where the blocked artery is completely removed and replaced with a new one taken from different parts of the body. Non surgical methods include taking drugs that cause vasodilation such as glyceryl trinitrate which converts into nitric oxide and hence dilates the coronary artery causing an increase in blood flow. Beta adrenergic blocking receptors are used to reduce the heart rate and therefore causing a reductio n in cardiac output. Other techniques that involve the use of calcium channel blockers that are used for vasodilation and hence helping the flow of blood.ConclusionThe heart is a an electromechanical pump which carries out its action through pulmonary and systemic circulation. The pumping action is well synchronised such that there is proper blood flow within the heart and outside to carry out haemodynamic activities. The transportation of blood is carried by a system consisting various networks that are spread throughout the body known as the cardiovascular system. This system helps in the transportation of oxygen to different tissues in tell apart to carry out different metabolic activities. The exchange of oxygen between tissues and the cardiovascular system takes place through a process called diffusion. The effects of reduced blood are many and can lead to a condition known as ischemia. Angina pectoris is one of the main problems that can cause due to reduced blood flow and he nce causing a sever pain in the chest region and on sever reduction in blood flow it may even lead to myocardial infraction which ultimately leads to death. There are numerous treatments for curing this particular problem, it may be either through surgical methods which includes cardiopulmonary bypass and angioplasty or using drugs that increase vasodilation and decrease cardiac output. These drugs include beta receptors, calcium channel blockers and nitroglycerin.

Teaching Philosophy :: Education Teachers Essays

Teaching Philosophy I was held back in fourth grade, because my instructor failed to realize that I was struggling. My parents tried everything from money incentives to grounding me until my work was done. nothing seemed to work with me I didnt understand what I was supposed to be learning and no amount of pressuring, grounding, or incentives were going to help. The second time around, my teacher didnt put as much pressure on me and made the class a little more interesting. The following year, my teacher Mr. Barger, told us on the first day that hed give us just enough rope to hang ourselves. I often found myself in such a position. This teacher is the best teacher I have ever had, because he made the class fun. By the end of the year I was on the B honor roll. It wasnt until my senior year in high school that I decided I wanted to be a teacher. I established that I wanted to give something back to the students. I wanted to become the teacher that students would remember for making a difference in their life. I debate that the nature of knowledge is constructed and dependent upon person, place, or time. Knowledge depends upon the teachers teaching styles, foundations, and how much time the teacher can allow for certain subjects. With the student, it depends on his/her age, their learning process, and their learning environment. How well he/she does can depend on how much time the teacher spends on the subject. You could have a slow squirt in a class, but if you spend just a little longer on that math problem they just whitethorn get it. You may have a six-teen year old boy who chooses not to learn and goofs off, but if you keep trying to capture his interests hell probably come around. The nature of knowledge is relative it just depends on how much the teacher and the student want to put into it. I believe that public education was established so that all people could get an education.

The Selfishness Of Man in Steinbecks Grapes of Wrath Essay -- essays

The Selfishness of ManCultural and economical pressures often lead people to behave corruptly. In John Steinbeck?s novel, The Grapes of Wrath, set in the dustbowl era, people act out of greed rather than out of consideration or kindness. Tom Joad and his family have been step on it off their land by inconsiderate, m aney hungry businessmen who do not c ar about the impact homelessness will have on the evictees. The history revolves around the Joad Family?s trip (joined by former preacher Casey) from Oklahoma to California, along route 66, where they expect to find work. Though Casey and the Joads are goodhearted and honest people, they are the victims of dishonesty and dupery when they realize that the jobs they have come so far to acquire pay them much less than they were originally promised. The book focuses on the family?s struggle to survive, while exhibiting the evil and manipulative power which the live owners and businessmen of the era possessed. Throughout the novel, Stein beck demonstrates the impacts and consequences of mans selfishness and inhumanity by exemplifying the unsavoury and egotistical actions of the tenant owners and businessmen.In the beginning of the novel, before Casey and the Joads set out on their journey, the selfishness and inhumanity of the businessmen and tenant owners becomes apparent. In one of the ?plotless? chapters, the reader is exposed to the hardships which the farmers are coerce to face while being evicted from their land. Businessmen, sent from the bank, would come to the farmers land in cars and explain to the farmers that they need to get off their land. They would tell the farmers that unfortunately, with the technological advances being made, a tractor can do the work of twelve families- h... ... rendering the much needed food useless. The inconsiderate actions displayed by the businessmen and orchard owners show their selfishness and inhumanity, and exemplify their disregard and indifference towards suffering humans.Steinbeck portrays the wealthy men of the era as heartless and egotistical people who only care for themselves. His message through the portrayal of these wicked men is one of simplicity, egotism, greed, selfishness, and heartlessness are all traits which a man shouldn?t possess. The themes which run throughout the novel are as valuable immediately as they were in the mid 1900?s, and Steinbeck urges his reader to recognize that. His depiction of the selfishness of man serves to teach about human nature, and by acknowledging the harmfulness of the greedy and corrupt businessmen, one can learn how to act morally and ethnically responsible.
