Human Digestive System

The human digestive system is a complex series of organs and glands that processes food.

In order to use the food we eat, our body has to break it down into smaller molecules that it can absorb and use as energy or as building blocks for other substances.

The digestive system is made up of the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.

It also includes several accessory organs, such as the liver, pancreas, and gallbladder, which produce enzymes and other substances that aid in digestion.

The process of digestion begins in the mouth, where food is mechanically broken down by chewing and mixed with saliva.
