Question

Choose the correct answers from the alternatives given.
The villi present on the wall of the small intestine

• A. secrete digestive enzymes
• B. increase the surface area for absorption
• C. hold mucus, so ulcers do not form
• D. hold products of digestion, so they do not enter the large intestine

Answer 1

The correct option is B increase the surface area for absorption

The absorption of digested carbohydrates, proteins and fats is done in the small intestine with the help of villi which helps increase the surface area of the intestine. Villi are finger like projections on the intestinal wall that absorbs digested food material. Carbohydrates and proteins are absorbed into blood, while fats are absorbed into the lymph

So, the correct answer is 'increase the surface area for absorption'
