Detailed explanation-1: -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.
Detailed explanation-2: -The stomach secretes gastric juice, which contains hydrochloric acid.
Detailed explanation-3: -Gastric secretion is stimulated by the act of eating (cephalic phase) and the arrival of food in the stomach (gastric phase). Arrival of the food in the intestine also controls gastric secretion (intestinal phase). The secreted fluid contains hydrochloric acid, pepsinogen, intrinsic factor, bicarbonate, and mucus.
