Stomach function?

Stomach function?

• A. Breaks down food with acid and enzymes
• B. Absorbs most nutrients
• C. Produces bile
• D. Gas exchange

Answer: (A)

The stomach’s main job is chemical and mechanical digestion to break down food. It uses hydrochloric acid to create a very acidic environment and activates enzymes like pepsin to start digesting proteins. In addition, the stomach churns and mixes food with these secretions, turning it into a semi-liquid chyme that moves toward the small intestine. This combination of acid and enzymes is what truly breaks down the food there. Bile production happens in the liver (bile helps digest fats), gas exchange occurs in the lungs, and while some substances can be absorbed in the stomach, most nutrients are absorbed in the small intestine. So the statement that best describes the stomach’s function is breaking down food with acid and enzymes.
