血液循环是人体重要的生理机能之一。循环障碍,血流减少,可致组织缺氧与新陈代谢失常,严重者可危及生命。循环障碍除因解剖学上的血液循环发生梗阻所致者外,还可由血流动力学的改变所引起。本文简要的复习了血液流变学的基本概念,并着重讨论在一些血液病中的血液流变学的改变。一、血液粘度及其决定因素血液流变学是研究血流的性质,其中最重要的内容是血液粘度,即流体的相互作用。当血液在血
Blood circulation is one of the body’s important physiological functions. Circulation disorders, blood flow can cause hypoxia and metabolic disorders, serious cases can be life-threatening. Circulatory disorders in addition to anatomical blood circulation obstruction caused by, but also by the hemodynamic changes caused. This article briefly reviews the basic concepts of hemorheology and focuses on the changes in hemorheology in some blood diseases. First, the blood viscosity and its determinants Hemorheology is the study of the nature of blood flow, the most important part of which is the blood viscosity, the fluid interaction. When the blood is in the blood
