Explanation:
Detailed explanation-1: -Hydrochloric acid secreted from gastric parietal cells generates the strongly acidic environment of the gastric lumen (pH <2) (305), which kills food-derived bacteria, facilitates food digestion, and promotes absorption of minerals including phosphate, calcium, and iron.
Detailed explanation-2: -Hydrochloric Acid Production HCl is produced by the parietal cells of the stomach.
Detailed explanation-3: -Gastric HCl is secreted from the highly specialized parietal cells located in the corpus of the stomach, generating a H+ concentration in the gastric juice that is 3 million times greater than that in blood and tissue. The process is controlled by a complex system of endocrine cells and neurons.
