The digestive system breaks down food through mechanical and chemical processes. The oral cavity and esophagus mechanically break down food through chewing and peristalsis moves food to the stomach. The stomach, liver, pancreas, small intestine and large intestine then use enzymes and digestion to extract nutrients from food for absorption and elimination of waste.
