What will happen to faeces if water is not absorbed in the large intestine?
Answer and explanation
Correct answer: Faeces may become more watery
The governing concept is water reabsorption during digestion. The large intestine removes a considerable amount of water and some salts from undigested material, helping faeces become more solid before elimination. If this absorption is greatly reduced, excess water remains in the intestinal contents, so the faeces may be loose or watery. Thus option A is correct; the other options describe impossible changes or unrelated functions.
