Abstract
At relatively low perfusion rates, anoxic regions may occur in tissue even though oxygen remains in the blood as it leaves the capillary at the venous end. In this paper a mathematical theory of facilitated diffusion is developed and used to determine the extent to which myoglobin increases the removal of oxygen from blood and aids in the reduction or elimination of regions of anoxia.
摘要
在相对较低的灌注速率下，即使血液在静脉端离开毛细血管时仍含有氧气，组织中仍可能出现缺氧区域。在本文中，我们发展了一种易化扩散的数学理论，并用于确定肌红蛋白在多大程度上增加了从血液中摄取氧气的能力，以及有助于减少或消除缺氧区域。
