Diarrhoea occurs when
- A. the large intestine absorbs too much water
- B. digestion proceeds too rapidly in the stomach
- C. the intestinal contents move too quickly for adequate water absorption
- D. the villi absorb too much glucose
Explanation
When contents rush through, the large intestine cannot reclaim enough water and the faeces stay liquid, risking dehydration. Too much absorption has the opposite effect, causing constipation.
