Weighing about 3 pounds and reddish-brown in color, the liver serves a variety of critical metabolic functions, acting as a factory, warehouse and gatekeeper, among other responsibilities.

It contains cells with special enzymes that can break down toxic substances into non-toxic forms. These are removed in the liver from amino acids, freeing the acids for use in carbohydrate and far metabolic pathways. This comment form is under antispam protection.

The liver converts glucose to a storage form of the molecule called glycogen , which is really just a long chain of glucose molecules. While the liver is primarily located in the right and central upper parts of the abdomen, the path of nerves in the abdomen can sometimes cause liver pain to manifest on the left side, or even in the lower abdomen. The hepatic artery is like any other artery in that it carries oxygenated blood to the liver and nourishes its cells with oxygen and nutrients.

The liver is also extremely active in fat metabolism.
