Why can faeces become watery if water absorption in the large intestine stops?
Answer and explanation
Correct answer: Water will not be reabsorbed from undigested material.
The governing concept is water reabsorption in the large intestine. After most digestion and nutrient absorption are complete, the large intestine removes a substantial amount of water and salts from the remaining material. If this process stops, excess water stays mixed with the waste, making faeces loose or watery. Option A correctly explains the result; the other choices involve unrelated organs or impossible chemical changes.
