Anatomy The liver is one of the main organs of digestive schema which is ruby-reddish brown in color. coloured is the largest gland of the body which produces different hormones. Liver is divided into ii lobes right and left lobe on th e anterior and posterior surface. On the inferior surface the liver has two small lobes quadrate lobe and caudate lobe between the right lobe and the left lobe. In between the caudate lobe and the quadrate lobe is porta hepatis which receives hepatic portal vein, hepatic artery proper and common saddle sore duct. Liver receives blood by two blood vessels hepatic artery and portal vein. The parenchyma of liver is made up of epithelial cells called hepatocytes. Blood sinusoids are present in between hepatocytes which are known as hepatic sinusoids. admission area is a space which contains three tubular structures collectively called portal triad. The portal triad contains a branch of portal vein, a branch of hepatic artery and bile duct. A delicate cover charge is present around the parenchyma of liver known as Glisons capsule. The liver performs different metabolic functions. Liver helps in protein synthesis like albumin which helps in regulating osmotic pull. Liver synthesize f actor I which helps in blood clotting. Liver produces globulin which helps in immunity. In prolific metabolism liver plays important role. It synthesizes cholesterin and also performs lipogenesis. On the other hand liver produces bile which is necessary for the emulsification of fat which is breakdown of fat so liver plays role in synthesis and breakdown of fat. Bile is then transported to gall vesica for storage. From gall bladder the bile goes to the duodenum for fat emulsification when fat reaches the duodenum for digestion. Liver also plays important role in carbohydrate metabolism as gluconeogenesis, glycogenolysis and glycogenesis occur in liver. Liver also stores the extra glucose in form of glycogen. Thrombopoietin is hormone which is also produced in liver. The function of thrombopoietin is the regulation of platelets production in bone marrow. The liver helps in the breakdown of different substance like insulin, hemoglobin, different drugs and ammonia etc. During the fir st three months of foetal life the liver produces red blood cells. Liver also plays role in blood pressure regulation because it produces angiotensin hormone (Robbins et al 2005). Abnormality By attacking liver cells the hepatitis C virus make morphological changes in the tissues of liver. The hepatitis C virus starts necrosing the liver cells and causes the shrinkage of the liver. The liver becomes wrinkled and red in color. Cross sectional examination of the necrosed liver shows muddy red appearance and blotchy bile staining. There is complete destruction of
