alimentary canal

The alimentary canal is an important biological term that refers to the entirety of the digestive system. Essentially any part of the body that comes in contact with food is considered to be a part of the alimentary canal. The canal begins in the mouth. It then connects to the esophagus, which moves the food via peristalsis down to the stomach. At the stomach, the food is digested and dissolved using the powerful acids and muscle contraction of the stomach muscles. Following this, the used up food then moves into the intestines, where the digested food is absorbed by the body. Finally, the food passes out of the intestinal system to the final part of the alimentary canal, where the food is eliminated out of the anus.
