Detailed explanation-1: -The stomach: The stomach is a thick-walled muscular bag. Its shape is like a flattened U and it is the widest part of the alimentary canal. The inner lining of the stomach secretes mucous, hydrochloric acid, and digestive juices.
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: -Stomach. The stomach wall produces gastric juice (hydrochloric acid and enzymes) that digests proteins. The stomach acts like a concrete mixer, churning and mixing food with gastric juice to form chyme-a thick, soupy liquid.
