The digestive system breaks down raw food into nutrients and removes waste. It includes the mouth, esophagus, stomach, liver, large intestine, rectum, and anus. The mouth chews food and the esophagus transports it to the stomach. The stomach contains acids and enzymes to digest food and the liver produces sugars and other substances. The large intestine collects food waste and the rectum stores feces before it exits through the anus.
