What is the main function of mucus in the stomach?
Answer and explanation
Correct answer: To protect the stomach wall
Mucus secreted by the stomach forms a protective coating over its inner lining. This barrier reduces direct contact between the stomach wall and hydrochloric acid or digestive enzymes, preventing self-digestion and irritation. The heart pumps blood, plants release oxygen during photosynthesis, and kidneys form urine; none of these is the function of gastric mucus. Thus option A is correct.
