Where does digestion of food normally begin in humans?
Answer and explanation
Correct answer: Mouth
The governing concept is the sequence of human digestion. Food first enters the mouth, where the teeth mechanically break it into smaller pieces and the tongue mixes it with saliva. Salivary amylase begins the chemical digestion of starch there. Thus option A, the mouth, is correct. The stomach and small intestine continue major stages of digestion, while the large intestine mainly absorbs water and forms faeces.
