Epithelium and Connective Tissue,
Mucosa of Stomach
This image shows the simple columnar epithelium and loose connective tissue that form the surface of the stomach mucosa.
The epithelial tissue layer of the stomach provides protection against digestion by producing sticky mucus. The epithelial surface contains many shallow indentations, called gastric pits, which open at the bottom into gastric glands (not shown here).
The connective tissue layer of this or any mucosal surface is called lamina propria. Lamina propria is a loose connective tissue with a relatively high proportion of cells. The defensive cells of the immune system are more numerous here, close to a vulnerable surface, than in ordinary loose connective tissue deeper in the body. Capillaries are usually abundant in lamina propria.
