Detailed explanation-1: -There is significant chemical digestion in the stomach. Two types of glands exist in the gastric mucosa that aid in chemical digestion: oxyntic glands and pyloric glands. Oxyntic glands are located in the body of the stomach and contain parietal cells and chief cells.
Detailed explanation-2: -The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.
Detailed explanation-3: -Secretions. The abomasum is the only stomach compartment with glandular mucosa that can secrete digestive juices, including hydrochloric acid, pepsin, and rennin. Alkaline chyme stimulates abomasal emptying, and acidic chyme inhibits emptying via release of local peptides and hormones.
Detailed explanation-4: -The glands in the stomach lining produce stomach acid and an enzyme that digests protein.
