How does the Digestion System Work?

The digestive system is a series of hollow organs joined in a long tube that starts at the mouth and ends at

the anus. Inside the 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. The digestive juices are used

to turn swallowed food into a substance that the body can use, and this substance travels through your small

intestine, where the proteins are absorbed through the walls and used, and whatever isn’t used is disposed

of.
