Why is the small intestine suitable for both digestion and absorption?
Answer and explanation
Correct answer: Digestive juices enter it and villi increase surface area
The governing concept is the division of functions in the small intestine. Digestive juices from the pancreas and intestinal glands complete the breakdown of carbohydrates, proteins and fats. The lining has numerous villi with thin walls and blood capillaries, giving a large surface for rapid nutrient absorption. Hence option A is correct; the other choices describe neither the main role nor the structure of the small intestine.
