Human Digestive System - Free Essay Examples and Topic Ideas

The human digestive system is responsible for breaking down ingested food into its constituent molecules, which can then be absorbed into the bloodstream for use by the body. It consists of organs such as the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus, each of which serves a specific purpose in the process of digestion. Various enzymes and acids are involved in breaking down food as it moves through the digestive tract, while muscles throughout the system help move food along and mix it with digestive secretions. Finally, waste products are eliminated from the body through the rectum and anus as solid feces.
