Anatomy

Swallowed food goes through the esophagus,which is the feeding tube.Next, food enters the stomach, where it is digested.
Digested food travels from the stomach to the small intestines, where most nutrients are further digested and absorbed into the body.
Fibers and digested food finally reach the colon. In the colon, the rest of the nutrients get absorbed and stools are formed. Stools are stored in the last part of the colon, the sigmoid and rectum, before being excreted.The colon has several sections:









The walls of the intestines have 3 layers. The inside layer is called mucosa; it is responsible for digesting and absorbing food. The middle layer of the intestines is muscle that helps push food through. The outer layer of the intestines is called serosa. The serosa is very smooth, so the intestines do not get stuck together in the abdominal cavity.
