The human digestive system consists of the mouth, esophagus, stomach, small intestine, large intestine, and rectum. Food moves through this system where it is broken down and absorbed. The small intestine plays an important role in digestion through villi and microvilli that increase surface area for absorption. Glands like the salivary glands, pancreas, and liver secrete enzymes to further break down food into molecules that can be absorbed and used by the body.
