Final answer:

The stomach produces gastric acid and mucus to aid in digestion.


Explanation:

Gastric acid, mainly hydrochloric acid, is a substance produced by the stomach that helps create an acidic environment necessary for the activation of the protein-digesting enzyme pepsin, initiating protein digestion. Mucus is another substance secreted by the stomach lining that forms a protective coating to prevent damage from gastric acid and aid in the smooth passage of food.
