Digestive System

The digestive system is a long tube that begins at the mouth. After food is swallowed, the food passes through a tube includes the stomach and the intestines. The food is ground and mixed with digestive juices, that have chemicals in them that help break down the food. When the tiny bits of food go into the stomach, they are churned to break them down even more. Then the food bits go into the small intestine, a long tube below the stomach.
