About Your GI Tract

Your digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Inside this tube is a lining called the "mucosa." In your mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help you digest food. The digestive tract of a typical adult is about 30 feet long.

Two solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (such as nerves and blood) play a major role in the digestive system.
