Quizplus · Accepted Answer

The gastric glands in the stomach mucosa secrete hydrochloric acid, pepsinogen (which begins the digestion of protein), and intrinsic factor, which is needed for the absorption of vitamin B₁₂. Salivary amylase, an enzyme released by the salivary glands, mixes with the food and begins carbohydrate digestion. Bile acids emulsify fat, that is, they break down large fat molecules into smaller molecules that can be chemically digested by fat enzymes.
