The 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 the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food.wo 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 vessels) play a major role in the digestive system.
