Liver

The liver is the largest of the body's glands and is responsible for several important functions. Weighing about three pounds, the red-brown organ features a high degree of vascularity which is responsible for its dark color. Located mostly on the right side of the abdominal cavity, just above the duodenum, the liver aids in the digestion of fats by secreting bile into the duodenum.

The liver also destroys red blood cells, forms urea for the excretion of nitrogenous wastes, forms fibrinogen, used in blood coagulation, stores glycogen, helps in the metabolism and storage of vitamins, and produces protective and antitoxic substances, among its many functions.
