Gastric Glands
Chemical digestion in the stomach is achieved by secretions from oxyntic and pyloric glands that break down proteins.
Oxyntic glands are found in the body of the stomach, and contain chief and parietal cells.
- Chief cells secrete pepsinogen.
- Parietal cells secrete HCL & Intrinsic factor.
- Mucous cells secrete bicarbonate-rich mucus, which protects stomach lining from acids.
- G-cells secrete gastrin, which stimulates parietal cell secretion of HCL.
