WebPrimary Hemostasis. This term refers to the response to vascular injury that produces a platelet clot at the site of damage. 1,2 Primary hemostasis serves to immediately limit bleeding through the formation of a loose platelet plug. Platelets play a key role in the rapid response to blood vessel injury by: WebHemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, in which clotting factors promote the formation of a fibrin clot. Fibrinolysis is the process in which a clot is degraded in a healing vessel. Anticoagulants are substances that oppose coagulation.
