Gastric pits are indentations in the stomach which denote entrances to 3-5 tubular gastric glands.[1][2] They are deeper in the pylorus than they are in the other parts of the stomach. The human stomach has several million of these pits which dot the surface of the lining epithelium. Surface mucous cells line the pits themselves but give way to a series of other types of cells which then line the glands themselves.
