A diagram showing the intestines of a person

The intestines of an animal are like a hollow tube so that food and bile from the stomach can reach the rectum. They also take any useful compounds from the digested food through small villi or tiny microvilli.[1] These are very small, hair-like structures in the walls of the intestine. It is also called bowel and is part of the alimentary canal between the stomach and the anus.[2]
