The mammalian gas exchange system is efficient due to the large alveolar surface area, constant ventilation, short diffusion distances, and a rich blood supply maintaining steep concentration gradients.
The mammalian gas exchange system is efficient due to the large surface area of alveoli, continuous lung ventilation, short diffusion distances, and a dense capillary network maintaining a steep concentration gradient.
