当人们考虑 O2 从大气转移到线粒体的途径时,经典地确定了几个不同且连续的步骤:1)通过通气将 O2 的对流气流输送到肺泡。 2) 扩散气体混合并穿过血气屏障转移到毛细血管血液中,3) 血液中的对流输送到周围组织,以及 4) 从组织毛细血管扩散到利用 O2 的线粒体。
When one considers the pathway for transfer of O2from the atmosphere to the mitochondria, several distinct and sequential steps are classically identified: 1) convective gas flow of O2to 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 O2is utilized.
