人体的心血管系统是一个具有复杂分支而又非常完整的管道系统,无论是动脉、静脉或毛细血管,内壁都覆盖着一层内皮细胞,极其光滑。在生理状态下,血液以液体状态在这条管道中循环流动;但是在某些因素作用下,血液成分发生凝集现象,形成固体团块,这个过程就叫作血栓形成,形成的团块就叫作血栓。血栓形成是临床实践过程中经常遇到的问题,了解血栓形成发生的原因和条件可防止其发生。引起血栓的主要原因有三: 首先是血管壁的损伤,血管内 The human cardiovascular system is a complex and very complete branch of the pipeline system, whether it is arteries, veins or capillaries, the inner wall is covered with a layer of endothelial cells, extremely smooth. Under physiological conditions, blood circulates through the tube in a liquid state; however, under certain conditions, blood components aggregate to form solid agglomerates. This process is called thrombosis and the formation of lumps is called For thrombosis. Thrombosis is a common problem encountered in clinical practice, to understand the causes and conditions of thrombosis prevent it from happening. Thrombosis caused by three main reasons: first, the damage of the vessel wall, intravascular
