Hemostasis - Wikipedia
WebIn biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction; temporary blockage of a hole in a damaged blood vessel by a platelet plug
Hemostasis: Stages and How the Process Stops Blood Flow - Cleveland Clinic
WebHemostasis is your body’s natural reaction to an injury that stops bleeding and repairs the damage. This capability is usually for your benefit, conserving blood and preventing infections. In rare cases, the process doesn't work as it should, and this can cause problems with too much or too little clotting.
