The alveolar membrane is the gas-exchange surface.
2.
Thus will have a high diffusion out and O2 will have a low diffusion through the alveolar membranes and into the blood.
3.

4.
A three-layered pellicle lies beneath the plasma membrane and is otherwise composed of the alveolar membranes and widely separated microtubules that arise subapically.
