Question

Quizplus · Accepted Answer

Parietal cells secrete hydrochloric acid, which helps to break down ingested food and activates pepsinogen into its active form, pepsin. Parietal cells also secrete intrinsic factor, which is necessary for the absorption of vitamin B12. Gastric lipase is secreted by chief cells, not parietal cells. Pancreatic amylase is secreted by the pancreas, not the stomach. Cholecystokinin is a hormone secreted by the small intestine, not the stomach.
