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现象，其核心在于血液形成血栓。此过程对于止血（即停止受损血管出血）至关重要，其中受损的血管壁被血小板和含纤维蛋白的血栓所覆盖，以实现止血并启动受损血管的修复。凝固功能紊乱可能导致出血（出血）或血栓形成（血栓症）的风险增加。来源：[维基百科凝固条目](https://zh.wikipedia.org/wiki/Coagulation)
