Answers are hydrochloric acid. Pepsin, an enzyme that digests proteins. Enzymes that digest lipids.
The innermost layer of the stomach is known as the mucosa, and is made of mucous membrane. The mucous membrane of the stomach contains simple columnar epithelium tissue with many exocrine cells that secrete hydrochloric acid and two digestive enzymes pepsinogen and gastric lipase. Pepsinogen is the precursor molecule of the protein-digesting enzyme pepsin. Gastric lipase digests lipids.
