Short note on liver

The liver is one of the digestive glands and plays an important role in the digestive system. It is the largest gland of the human body. It is located in the abdominal cavity. The liver is connected to the two following large blood vessels.
(i) Hepatic vein – It is used to carry the blood, which is rich in oxygen.
(ii) Portal vein – It is used to carry the blood, which is rich in digested nutrients.
The liver consists of two hepatic lobules which are made up of hepatic cells. Lobules are the structural and functional unit of the liver. Each lobule is overlaid by the Glisson’s capsule which is a thin connective tissue. Hepatic cells secrete the bile and pass into the gallbladder through the hepatic ducts. The hepatic duct from the liver and cystic duct from the gallbladder forms the common bile duct.
