The mechanism involves the active transport of hydrogen ions (H+) and chloride ions (Cl-) against their concentration gradients. During the gastric phase, the physical presence of food stretches the stomach walls, further activating mechanoreceptors.

Furthermore, the acidic chyme entering the duodenum stimulates the release of secretin, a hormone that prompts the pancreas to release bicarbonate-rich fluid to neutralize the acid in the small intestine, protecting its delicate lining. This intricate feedback loop ensures that acid and enzyme production is ramped up precisely when and where they are needed most.
The hydrogen ions are pumped into the stomach lumen via the H+/K+ ATPase pump, while chloride follows passively, resulting in the formation of hydrochloric acid. These cells synthesize and secrete pepsinogen, an inactive zymogen that serves as a safeguard against the premature digestion of the chief cells' own protein machinery.

Factors Influencing Gastric Secretion. Upon release into the gastric lumen, pepsinogen encounters the acidic environment created by hydrochloric acid.
