noticeable symptoms for as long as one to two decades after they are infected. In fact‚ by the time symptoms appear‚ the virus has probably already begun to damage the liver. If the liver is injured and stops functioning‚ death will always be the outcome (Lieber). Liver failure from chronic hepatitis C is one of the most common causes of liver transplants in the United States. Hepatitis C is an inflammation of the liver’s cells and tissues caused by the hepatitis C virus (HCV). Hepatitis C virus is

The liver is a vital organ within the human body. The normal pathophysiology of the liver is to perform critical functions which rid the body of harmful toxins and substances. The liver rids the body of its harmful toxins by the way it secretes chemicals and produces bile. Bile is a substance that helps the breakdown of lipids and salts so that they are easily absorbed into the intestine to be secreted out of the body. Vasodilators are medications which cause the blood vessels within the human body

individuals that are in the pre listing stage of liver transplants one main aspect to address is educating the patient and the family. One of the main nursing interventions is teaching patients and their family the importance of abstinence from both alcohol and tobacco if it is used. The continued use of alcohol can cause worsening condition of the patient’s current liver in addition to being a reason as to why the patient is no longer eligible for liver transplant (NIDDK‚ 2012). If the patient uses

Give your reasons and outline any assumptions that lead you to this hypothesis. I’m guessing that the liver will turn the peroxide into something else‚ or make it change.

HEPATITIS B VIRUS 2 HEPATITIS B VIRUS Hepatitis B is a viral infection that is caused by the hepatitis b virus (HBV). It is a serious inflammatory condition of the liver. There are two types of hepatitis B which are acute and chronic. When a person first becomes infected with the virus it is known as an acute infection. Depending on how the persons body reacts to the virus determines whether or not they exhibit any symptoms

disease is an inherited disorder were extra copper builds up in the liver‚brain and eyes. Wilson’s disease is an autosomal recessive trait. (Autosomal recessive trait: means two copies of an abnormal gene must be present in order for the disease or trait to develop) Wilson disease is located on chromosome 13. The gene is called ATP7B and it contains the genetic information necessary to make a copper transport copper out of the liver. Mutations in the gene lead to an abnormal copper transport

Introduction: In liver cells‚ hydrogen peroxide is produced as a bi-product of some metabolic reactions. Hydrogen peroxide is a highly active chemical used in household products for bleaches and cleansing wounds. In a cell its build up would be highly toxic. However‚ liver cells contain an enzyme‚ catalase‚ which immediately breaks down hydrogen peroxide. It is a peroxidase and breaks up the toxic hydrogen peroxide to water and oxygen which are both nontoxic. The reaction is exothermic‚ meaning that
