Abstract
When one considers the pathway for transfer of O2 from the atmosphere to the mitochondria, several distinct and sequential steps are classically identified: 1) convective gas flow of O2 to the alveoli by ventilation. 2) diffusive gas mixing and transfer across the blood gas barrier into the capillary blood, 3) convective transport in the blood to the peripheral tissues, and 4) diffusive movement out of the tissue capillary to the mitochondria where O2 is utilized.
