Describe and explain two ways in which alveoli in the mammalian lung are adapted for efficient gaseous exchange
-
Alveoli in the mammalian lung are thin walled to allow the quick passage of gases, for example oxygen and carbon dioxide.
-
Alveoli in the mammalian lung have a large surface area which allows for the diffusion of multiple gas molecules simultaneously, thus increasing the speed of diffusion across their surface.
