血管运动(V asom otion)是机体在生理条件下自然发生的管径在100μm以下的细小血管处具有一定频率和振幅的周期性节律性的内径收缩与舒张现象。血管运动对机体来说具有重要的生理意义,它不仅是引起毛细血管内红细胞间歇流的主要原因;还能调节下游毛细血管的血流速度;改变血液粘
Vasomotion is a cyclical rhythmic contraction or relaxation of internal diameter with a certain frequency and amplitude at a small blood vessel with a diameter of less than 100 μm that naturally occurs under physiological conditions. Vascular movement of the body has an important physiological significance, it is not only caused by intracerebral capillary red blood cell intermittent flow of the main reason; also regulate the downstream capillary blood flow velocity; change the blood viscosity
