Liver Essay Example | Topics and Well Written Essays - 2000 words

Liver - Essay Example These plates radiate from the central vein. Each of these plates is of thickness of two cells. Between the adjacent cells lie small bile canaliculi that empty into bile ducts in the fibrous septa separating the adjacent liver lobules. Blood from the venous outflow of the gastro intestinal tract reaches small portal venules in the septa by way of portal vein. Flat branching hepatic sinusoids, which lie between hepatic plates receive the blood from the portal venules. Afterwards the blood goes to central vein. Thus hepatic cells are continuously exposed to portal venous blood. In the interlobular septa, hepatic arterioles supply arterial blood to the septal tissues between the adjacent lobules. Many of these arterioles empty directly into the hepatic sinusoids in such a way that one third of the distance is away from the interlobular septa. The venous sinusoids are lined by two other types of cells namely, typical endothelial cells and larger Kupfer cells. The latter is also known as reticuloendothelial cells. The Kupfer cells are capable of phagocytosis, the process by which bacteria and other foreign matter in hepatic sinus blood are engulfed. The large pores in the lining of the endothelial cells facilitate free flow of the substances in plasma. Some pores are big enough to the tune of 1 micrometer in diameter. Millions of narrow tissue spaces called 'Spaces of Disse' lie between endothelial cells and hepatic cells. In the interlobular septa, these Spaces of Disse are connected with lymphatic vessels. Overflowing fluid in these spaces are thus removed by lymphatics. The large pores are helpful in diffusing even the large portions of plasma protein freely into this space. The functions of liver are versatile. Liver maintains filtration and storage of blood. Carbohydrates, protein, fats, hormones and foreign chemicals that are found in medications are metabolized at liver only. Liver stores vitamins and iron, which are necessary for the growth. The very important function of liver is formation of bile. It is through this bile secretion that many waste materials are excreted from liver. During medication, we consume many drugs such as sulfonamides, penicillin, ampicillin, and erythromycin. The active chemical medium present in liver detoxifies or excretes those drugs into bile. Accumulation of some steroid hormones like estrogen, coristol, aldosterone secreted by endocrine glands causes over activity of hormonal systems. Theses hormones are either chemically changed into other substances or excreted by the liver. Unwanted Calcium is excreted from the body only with help of the secretion from liver; from bile secretion the calcium reaches the gut and is lost finally in faeces. (Arthur C.Guyton and John E. Hall, 2000) One of the important excretory jobs carried out by the liver is removal of bilirubin. Bilirubin is formed continuously in the usual breakdown of the red blood cells. After circulating in the blood stream for about 120 days, in a normal healthy adult, the red blood cells wear out. These worn out red blood cells, haemoglobin, are converted into bilirubin, a yellow pigment. This bilirubin passes through the blood stream to liver, which is the only organ in our body capable of removing it. Metabolism of bilirubin takes places in three phases--- prehepatic, intrahepatic and post hepatic. In prehepatic phase about 80% of haemogulobin halves are metabolized to form bilirubin. Nearly 4mg/kg of bilirubin is produced in a

Argument for and against the Use of Death Penalty in Contemporary Amer Essay

Argument for and against the Use of Death Penalty in Contemporary America - Essay Example One of the opinions that support the implementation of the death penalty against capital offenders is its effectiveness in eliminating the criminals from the society. This effectively reduces rates of capital crimes by permanently eliminating the criminals from the targets. As opposed to imprisonment that often allows the criminals back to the society to induce high probability of further crimes, death penalty ensures complete elimination of the criminals from the society and hence reduces the rates of such crimes. The death penalty also identifies an economic advantage to the government that can then save its limited financial resources for social utilities instead of using the resources to maintain individuals who have been detrimental to the society’s utility. It, therefore, allows the government to focus on a single interest of providing the society’s utilities instead of dividing resources toward meeting utilities and maintaining individuals who have been detriment al to the government’s utility initiatives. The death penalty should also be implemented because of its retribution effect that not only punishes crimes but also derives utility from achieved justice to victims of capital crimes. Relatives and close friends of a murder victim will, for example, derive social and emotional utility from a death penalty against the murderer besides the general good of a safer society. The death penalty has also been supported for its effectiveness in discouraging criminals. This is major because people fear death and the associated pain. A person will, therefore, be more rational to refrain from a crime that attracts death penalty for fear of losing his or her own life as opposed to crimes that only attract fines or imprisonment, penalties that do not physically affect the criminals’ lives. There are however a number of augments that oppose implementation of the death penalty.  

Poetry Analysis Essay Example for Free

Poetry Analysis Essay Six Galician Poems by Federico Lorca (Madrigal for the City of Santiago, Ballad of Our Lady of the Boat, and Song of the Shop Boy) Lisability: Camellia-any of several shrubs of the genus Camellia, especially C. japonica, native to Asia, having glossy evergreen leaves and white, pink, red, or variegated roselike flowers. Veiled-not openly or directly expressed; masked; disguised; hidden; obscure: a veiled threat. Languishing-to be or become weak or feeble; droop; fade. Pampa-the vast grassy plains of southern South America, especially in Argentina. Nostalgia-a wistful desire to return in thought or in fact to a former time in ones life, to ones home or homeland, or to ones family and friends; a sentimental yearning for the happiness of a former place or time: a nostalgia for his college days. Story-The story is about Federico leaving his hometown of Madrid and going to Santiago. He arrives in Santiago Argentina, because several words he uses and other objects he describes are only found in Argentina. Lorca is in Santiago and it is constantly raining, it is raining at night and in the morning. If he is not writing about rain, it’s the ocean or some other form of water. While wondering the city he encounters a statue or painting of the Virgin Mary. He then travels to the capital of Argentina , Buenos Aires. He says the wind sounds like bagpipes. Ramon de Sismundi owns a shops and he seems to be unhappy throughout the whole poem. Meaning – Rain symbolizes a lot of things especially in poetry where there is not a real meaning. The rain Lorca rights about is cleansing him, starting a new life. All of the difficulties he had in Spain and America are now behind him, it is time for him to move on and start a new beginning. Many people are always stuck in the past, but he is not going to be like them, he is going to move forward and make progress. He also writes a whole poem about Our Lady of the Boat (Virgin Mary). She also represents various meanings, but in this poem he is most likely talking about pureness. A double emphasis since water is also pure. Also he may be trying to tell us that if it wasn’t for his strong faith in the Virgin Mary, he wouldn’t have the chance to move forward. He tends to write about nature, but the otherness of it. He talks about wind, which more than often symbolizes a certain type of force or energy. In Santiago the wind is damp and gray. Ramon is cleaning his shop, and dreaming but this man is still unhappy. He does not find the bagpipe winds of Buenos Aires, people that have positive and happy attitudes find great things about the city and move on, people who are depressed and unhappy such as Ramon do not get nowhere. Maybe Ramon is unhappy because he knows he is going to die, and it is sooner than he thinks. Lorca always seems to be expressing his inner emotions and feelings. Even though this place is great, there is no place better than home. Technique-Lorca is very big on imagery. Almost every single line contains imagery. He really tries to get the reader in the spot that he is at. Lines such as Trembles in my heart, and came the misty dead. He uses imagery to emphasize the meaning. Often, the intention of Lorca is to change the way readers see the world. Especially with Lorca’s themes, some of which include: awareness of death, our limitations, isolation and nature. He uses a lot of diction which is choosing certain words to emphasize something else, whether it is emphasizing the meaning or imagery. He also does not give no direct meaning. Mo or Pomo- Lorca is definitely a modernist poet. Not only in the pom but also in real life. He stuggles with the fact that he is homosexual and many people do not accept him, placing himself on the lower part of the hierarchy. Even though he is low on the hierarchy is doesn’t prevent him from making progress and moving on, leave everything else behind. These poems are modernist simply because of their appearance, they are very structured and have the same number of lines in each stanza, very formal.
