 Bulk transfer describes the movement of gases during inspiration and expiration within the proximal large airways.

 Diffusion is the passive movement of gases down the concentration gradient in the distal small airways to the alveolus. It is the process by which gases move (i) in and out of the alveoli into the terminal airways, (ii) across the alveolar capillary membrane, and (iii) between the blood and tissues.
