Question

Two villi surfaces are shown below. Which surface will be more effective in absorbing nutrients from the digested food in small intestine?

• A. Surface P will be more effective
• B. Surface Q will be more effective
• C. Both the surfaces will be equally effective

Answer 1

The correct option is B Surface Q will be more effective

Function of villi in small intestine is to increase the surface area for absorption. More surface area means better absorption.

From the 2 surfaces given, surface Q will have a greater surface area, thus more effective absorption.
