<prompt> Fibrin is degraded by-PlasminogenThromboplastinPlasminFD  <response>: Ans. is c i.e., Plasmin Fibrinolvtic system o Coagulation must be balanced with fibrinolysis to limit the hemostatic plug to the site of injury. o Injured vascular endothelium secret plasminogen activator that conves inactive plasminogen to active plasmin. o Plasmin breaks down fibrin resulting in production of fibrin degradation products. o Fibrinolytic system is regulated by plasminogen activator inhibitors PAIs that are secreted by endothelium.
