Once food is mixed with acid in your stomach, the food-acid mixture slowly enters the small intestine. The first portion of the small intestine is called the duodenum. It is here that the bile from the liver and the enzymes from the pancreas enter the intestinal tract to help digest the food. Here you can see two views of a normal duodenum.
