Health The liver is the largest solid organ and the largest gland in the human body. It carries out over essential tasks. Classed as part of the digestive system, the roles of the liver include detoxification, protein synthesis, and the production of chemicals that help digest food.

This MNT Knowledge Center article will cover the main roles of the liver, how the liver regenerates, what happens when the liver does not function correctly, and how to keep the liver healthy. Fast facts on the liver The liver is classed as a gland.

This capsule is further covered by the peritoneum, a membrane that forms the lining of the abdominal cavity. This helps hold the liver in place and protects it from physical damage.

Blood vessels Unlike most organs, the liver has two major sources of blood. The portal vein brings in nutrient-rich blood from the digestive system, and the hepatic artery carries oxygenated blood from the heart. The blood vessels divide into small capillaries, with each ending in a lobule.

Lobules are the functional units of the liver and consist of millions of cells called hepatocytes. Blood is removed from the liver through three hepatic veins.
