Question | Answer |
primary hemostasis | vasoconstriction, plt adhesion to exposed subendothelial connective tissue. plt aggregation to form initial plug at injury site. |
secondary hemostasis | coag factors interact on plt surface to produce fibrin. fibrin stabilization by factor XIII |
fibrinolysis | release of tissue plasminogen activator. conversion of plasminogen to plasmin. conversion of fibrin to fdp's |
