Blood clotting cascade

Coagulation is a complex process by which blood forms clots. It is an important part of hemostasis (the cessation of blood loss from a damaged vessel), wherein a damaged blood vessel wall is covered by a platelet and fibrin-containing clot to stop bleeding and begin repair of the damaged vessel. Disorders of coagulation can lead to an increased risk of bleeding (hemorrhage) or clotting (thrombosis). Source: [[wikipedia:Coagulation|Wikipedia]]

凝固过程是一种复杂的生理机制，通过该机制血液形成血栓。它是止血（即从受损血管中停止出血）的重要组成部分，其中受损的血管壁被由血小板和纤维蛋白组成的血栓所覆盖，以阻止出血并开始修复受损血管。凝固系统的失调可能导致出血（出血）或凝血（血栓形成）的风险增加。资料来源：[维基百科：凝固](https://zh.wikipedia.org/wiki/Coagulation)
