Digestive System: Anatomy
Overview
The digestive system includes the alimentary canal, a 30-foot long tube extending from the mouth to the anus. There are four layers that make up the tissue of the canal (with the exception of the stomach which has five). The digestive system includes accessory structures such as teeth, salivary glands, the liver, gall bladder, and pancreas.
