Even in the presence of red blood cells the viscous resistance of blood flow through narrow capillaries is only some 15-20% higher than that of pure plasma flow. The uniquely low "hydrodynamic disturbance effect" of the erythrocytes results from their similarly unique flow properties which allow them to adapt to capillary flow conditions by viscous deformation, orientation stability, and membrane rotation. In addition, the volume concentration of red cells decreases with decreasing vessel diameter, with the result that the majority of capillary vessels contains blood of an hematocrit which is less than 50% of the systemic value.
即使存在红细胞，血液在狭窄毛细血管中流动的粘性阻力也仅比纯血浆流动的阻力高约15% - 20%。红细胞独特的低“流体动力干扰效应”源于其同样独特的流动特性，这些特性使它们能够通过粘性变形、取向稳定性和膜旋转来适应毛细血管的流动条件。此外，红细胞的体积浓度随着血管直径的减小而降低，结果是大多数毛细血管中的血液血细胞比容低于全身值的50%。
