Your Digestive System

Your digestive system is made up of a series of organs that allows your body to get the nutrients and energy it needs from the food we eat.  As food travels through the digestive system it is broken down, sorted, and reprocessed before being circulated around the body to nourish and replace cells and supply energy to our muscles. This page includes an animation of the digestive process as well as a description of the various digestive organs and diseases related to them that we treat at the University of Michigan.
