Where are gastric glands present?name 3 major types of gland cells in gastric mucosa?

Gastric glands are present in stomach lining which has cells producing different type of secretions.

1. The chief or Peptic cells produce Protein digesting enzyme called as Pepsinogen.
2. Another type of cells called as oxyntic or parietal cells produce HCl and Castle Intrinsic factor. HCl is needed for activating Pepsinogen into pepsin (the active form). Castle intrinsic factor is important for absorbing Vitamin B12 from the food.
3. Mucous cells produce mucous which prevents the stomach lining from getting damaged by HCl.
