Protein digestion in the stomach results primarily from secretions released by the gastric glands. The enzyme that is secreted is called pepsinogen.
Protein digestion occurs in stomach only because it is safe for the body, as stomach has mucous secretions which prevents self digestion of stomach muscles by PEPSIN (enzyme for protein digestion) :)
The various hormonal secretions in the digestive process include: Secretin: From duodenum Chole-Cystokinin: From Gall Bladder Leptin: From Stomach These hormones help in the secretion of digestive enzymes and the CCK improves perisatalsis and amylase and lipase secretion from the liver. Leptin from stomach gives filling sensation from the stomach.
Many secretions that assist in digestion, but the most import is INSULIN.
Gastric juice is mixed with food in the stomach to promote digestion.
