|
|
II and III

Explanation:
Detailed explanation-1: -To exchange gases more efficiently the walls of the alveoli are thin which provide a larger surface area to make the exchange of gases properly. Hence, option II is the most appropriate.
Detailed explanation-2: -Large surface area to allow faster diffusion of gases across the surface. Thin walls to ensure diffusion distances remain short. Good ventilation with air so that diffusion gradients can be maintained. More items
