Feedback loops are when the body responds to signals, like insulin, that appear when the balance of something is off. When blood sugar is too high, insulin signals the liver to absorb more blood sugar, returning it to normal. When blood sugar is low, glucagon signals the body to release stored glucose to raise blood sugar back to normal.

Ingestion is when food comes into the body through the mouth and down the esophagus. Digestion begins with chemically with enzymes in saliva, and mechanically with the teeth, and continues when food (as a bolus) enters the stomach to be dissolved by acid and pepsin. Food (chyme) then goes into the small intestine where nutrients are absorbed through the villi. Waste is then eliminated through the large intestine, rectum, and anus.
