Lower digestive anatomy - illustration
Food passes from the stomach into the small intestine. In the small intestine all nutrient absorption occurs. Whatever has not been absorbed by the small intestine passes into the colon. In the colon most of the water is absorbed from the food residue. The residue is then eliminated from the body as feces.
