The Alimentary Canal

The digestion and absorption of food take place in a muscular tube that runs for over thirty feet (about nine meters) from the mouth to the anus. This is the digestive tract, sometimes referred to as the alimentary canal because we take our aliment (food) through it. It takes about fifteen hours for food to complete the trip through the alimentary canal.
