Much of mechanical digestion takes place in the
Correct answer: C. stomach
- A. oesophagus
- B. mouth
- C. stomach
- D. duodenum
Explanation
The correct answer is the stomach. The stomach is crucial for mechanical digestion as it churns and mixes the food, breaking it down into smaller pieces and converting it into a semi-liquid form known as chyme. This process is essential for the subsequent stages of digestion. In contrast, the oesophagus is merely a passage for food, the mouth begins mechanical digestion but does not complete it, and the duodenum primarily focuses on chemical digestion and absorption rather than mechanical breakdown.
