WebWhat are the adaptations of alveoli to increase gas exchange? Alveoli are folded to increase their surface area to volume ratio, so more volume of air can diffuse in from the blood and and in from the bronchioles. The lining of the alveoli walls are also moist so the gases can easily dissolve. The walls are thin so the diffusion distance is short. WebDiscuss how gases move across the alveoli.
