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. Depending on the section of the digestive tract, it protects the digestive tract wall, secretes substances, and absorbs the end products of digestion. It is composed of three layers: The epithelium is the innermost layer of the mucosa.
This tissue has cells that are clustered tightly. This tissue is avascular which implies that it should get nourishment through the diffusion of the substances from the connective tissue that is underlying via basement membrane. Types of Epithelia in Digestive tract. Epithelium lines up the digestive tube. The epithelium is continuous at skin located at mouth as well as anus. The nature of epithelium changes with body parts.
