WebbThere are three steps to the process: vascular spasm, the formation of a platelet plug, and coagulation (blood clotting). Failure of any of these steps will result in hemorrhage —excessive bleeding. Vascular Spasm When a vessel is severed or punctured, or when the wall of a vessel is damaged, vascular spasm occurs. WebbWhenever blood vessels are damaged, the loss of blood poses a considerable threat to homeostasis. Hemostasis is a positive-feedback mechanism initiated after vascular injury to stop or limit blood loss. There are three separate but interrelated processes involved in hemostasis: vascular spasm, platelet plug formation, and coagulation.
