What are three major types of cells found in the gastric glands? Name their secretions.
Gastric glands process three major types of cells namely (i) Mucous neck cells (Goblet cells) These cells are present throughout the epithelium of gastrointestinal tract and are involved in the secretion of mucus. (ii) Peptic or Chief cells (Zymogenic cells) These cells are usually basal in location and are involved in the secretion of gastric digestive enzymes such as proenzymes pepsinogen and prorennin. (iii) Parietal or oxyntic cells These cells are large and most numerous present on the side walls of the gastric glands. They are involved in the secretion of HCl and Castlis intrinsic Factor (CIF). (factor essential for the absorption of vitamin - B12 in ileum).
