Villi and alveoli are in different organs, yet what similar principle do they use?

Answer and explanation

Correct answer: They increase surface area to make exchange more effective

Villi increase the surface area available for nutrient absorption, while alveoli increase the surface area available for gas exchange. In both cases, the larger surface helps exchange occur effectively.
