The liver is the main warehouse for nutrients absorbed from the small intestine. Its job is to store, package and change these nutrients according to the needs of the body and then supply them to the blood stream for delivery to the various organs. The liver is a very large organ located in the upper right quadrant of the abdomen protected by the rib cage. It also produces bile which is stored in the gallbladder. Bile is necessary for the digestion and absorption of fat in the diet.
