Gastric pits

 ( Pits ) 

Gastric pits are in the stomach which denote entrances to 3-5 tubular gastric glands."gastric pits, that each open into four or five gastric glands", Quantitative Human Physiology 2E, 2017, Joseph Feher"Secretions from several gastric glands flow into each gastric pit" Principals of Anatomy & Physiology 15th Ed 2017, Gerard Tortora & Bryan Derrickson 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.

Gastric juice Gastric juice, containing gastric acid, is secreted from gastric glands, which are located in gastric pits. Gastric juice contains hydrochloric acid, pepsinogen and mucus. Hydrochloric acid is secreted by parietal cells, pepsinogen is secreted by gastric chief cells and mucus is secreted by mucous neck cells.
