(B) Stimulation of gastric secretion
Histamine is responsible for the first stage in the release of gastric acid. In order to carry out this process, histamine needs to couple to a special receptor on epithelial cells of the stomach, called parietal cells. After activation, the parietal cells secrete hydrochloric acid and intrinsic factor. This is how histamine helps in the secretion of gastric secretions .
