问:血流在血管里流动,什么样的力量对血管壁起作用?答:血流在血管里流动,对血管壁产生两种压力:1)环形压力:即对血管壁产生环形张力,也就是血压。过高的环形张力对血管起损害作用;2)切应力:即血流流动时对血管壁的摩擦力(图1),血流对内皮细胞有一定量切应力,对保持
Q: The blood flow in the blood vessels, what kind of power on the vessel wall? A: blood flow in the blood vessels, the vessel wall produces two kinds of pressure: 1) ring pressure: the ring that produces annular tension, also Is the blood pressure. Excessive ring tension on the vascular damage; 2) shear stress: the flow of blood flow on the wall friction (Figure 1), the blood flow to the endothelial cells have a certain amount of shear stress on the maintenance
