Gastric pits are indentations in the stomach which denote entrances to the gastric glands. 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.
Gastric juice
Gastric juice is secreted from gastric glands, which are located in narrow tube like structures called gastric pits. Gastric juice contains hydrochloric acid, pepsinogen and mucus in a healthy adult. Hydrochloric acid is secreted by parietal cells, pepsinogen is secreted by gastric chief cells and mucus is secreted by mucus neck cells.[1]
