How are reptile lungs different from human lungs?
All reptiles breathe through their lungs. The reptile lung has a much greater surface area for the exchange of gases than the lungs of amphibians. Many reptiles’ lungs have little sacs called alveoli, across which gas is exchanged. This makes their lungs much more efficient than those of amphibians.
