Structure of the Digestive Tract Wall The digestive tract, from the esophagus to the anus, is characterized by a wall with four layers, or tunics. The layers are discussed below, from the inside lining of the tract to the outside lining: The mucosa is a mucous membrane that lines the inside of the digestive tract from mouth to anus.
