Consider statements about human physiology: 1. The stomach digests proteins. 2. The small intestine absorbs nutrients. 3. The large intestine absorbs water. Which are correct? MCQ with Answer and Explanation

The stomach secretes gastric juice containing hydrochloric acid and the enzyme pepsin, which initiates the digestion of proteins into smaller peptides. The small intestine is the primary site for the final digestion of food and the absorption of most nutrients (amino acids, simple sugars, fatty acids, vitamins) into the bloodstream through its villi. The large intestine (colon) primarily absorbs water, electrolytes, and some vitamins produced by gut bacteria, forming solid feces. All statements are correct.
