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: -Parietal cells are present in glands within the fundus and body of the stomach and are the largest cells in these glands. They originate from immature progenitor cells in the gland isthmus and then migrate upward toward the pit region and downward toward the base of the gland.
Detailed explanation-3: -The above statement is a true statement. The parietal cells of the stomach do secrete HCL (Hydrochloric acid) and intrinsic factor. These cells are located in gastric glands which line the fundus and cardia of the stomach.
