Describe and explain two ways in which alveoli in the mammalian lung are adapted for efficient gaseous exchange

  1. Alveoli in the mammalian lung are thin walled to allow the quick passage of gases, for example oxygen and carbon dioxide.

  2. 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.
