-Functions of the Liver Essay The liver receives its blood from two main sources; the hepatic artery and the hepatic portal vein. The hepatic artery transports oxygenated blood from the left side of the heart through the aorta to the liver. The deoxygenated blood from the liver is drained back out through the hepatic vein which returns it to the vena cava. The hepatic portal vein carries nutrient rich blood from the small intestine to the liver. Its blood however‚ is already deoxygenated

Cirrhosis is defined histologically as a diffuse hepatic process characterized by fibrosis and the conversion of normal liver architecture into structurally abnormal nodules. In other words‚ The damaged hepatocytes regenerates‚ but the liver’s connective (scar) tissue regenerates faster. As a result‚ the liver becomes fatty and fibrous‚ depressing its normal activity. The scar tissue also obstructs blood flow throughout the hepatic portal system‚ causing portal hypertension. The progression of liver injury

Chapter 12: Cardiovascular System 12.1 3 types of blood vessels * Arteries: carry blood away from the heart to the capillaries * Capillaries: permit exchange of material with the tissues * Veins: return blood from the capillaries to the heart. Arteries Wall has 3 layers * Endothelium: inner layer‚ made up of simple squamous epithelium‚ with a connective tissue basement membrane that has elastic fibers. * Middle layer: thickest later and consists of smooth muscle that can

In due course of the journey‚ the ingested food is broken down by both physical and chemical means to release nutrients which are absorbed into the blood stream. The ingested food is physically broken down in the mouth
