Digestive System Functions

How does the digestive system function?

The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus (see figure). Inside this tube is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food.
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 (for instance, nerves and blood) play a major role in the digestive system.
