procedureThe clotting and scabbing phase of wound healing consists of three steps: (1) blood vessels around the wound narrow to reduce bleeding, (2) platelets clump together to form a plug in the wound, and (3) fibrin acts as 'blood glue' to create a net that holds the platelet plug in place, resulting in a scab.

procedureThe hemostasis phase of wound healing involves the following steps: (1) blood vessels in the damaged area constrict (vasoconstriction) to inhibit blood flow, (2) platelets are released and coagulate with fibrin at the wound site, and (3) the accumulation of platelets and fibrin forms a blood clot to seal broken vessels.
