what is the function of hcl secreted in the stomach
Gastric acid The highly acidic environment in the stomach lumen causes proteins from food to lose their characteristic folded structure (or denature). This exposes the protein's peptide bonds. The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis. In addition, many microorganisms have their growth inhibited by such an acidic environment, which is helpful to prevent infection.
Abdominal examination On light palpation, the examiner tests for any palpable mass, rigidity, or pain.
Cerebrum With the assistance of the cerebellum, the cerebrum controls all voluntary actions in the body.
