Blood from the intestines, rich in nutrients from digested food, flows to the liver. The liver is in the upper right of the abdomen, with most of it's bulk behind the lower right ribs. The reddish-brown, smooth-surfaced, wedge-shape liver has more than two hundred different task, mainly to do with metabolism (body chemistry). It breaks down some nutrients, builds up others, stores some until needed, and releases others when their levels in the blood fall to low.
