人体的凝血机制是一个复杂的生化反应,具有精密的调节机制,凝血机制中各系统相互作用,相互影响,相互制约,使凝血机制处于正常的平衡状态,研究表明血管内皮细胞在凝血机制中发挥重要作用,其具有抗凝和促凝双重作用,主动参与维持血液的液态性调节和凝血系统的激活,并通过内皮细胞本身产生的血管活性物质对血管张力起重要的调节作用.
The coagulation mechanism of the human body is a complex biochemical reaction with a sophisticated regulatory mechanism. Each system in the coagulation mechanism interacts, interacts and restricts each other so that the coagulation mechanism is in a normal equilibrium. Studies have shown that vascular endothelial cells play a role in the coagulation mechanism It plays an important role in anticoagulant and procoagulant activities. It actively participates in the maintenance of the fluid regulation of blood and the activation of the coagulation system, and plays an important regulatory role on the vascular tone by the vasoactive substances produced by endothelial cells themselves.
