The function of plasmin is to: hydrolyze fibrin. activate factor XII. promote platelet plug formation. control osmotic pressure of the blood. promote the formation of plasma.
hydrolyze fibrin.
Aspirin inhibits platelet plug formation by: blocking the binding of platelets to collagen. interfering with the synthesis of prostaglandins. blocking the effects of serotonin. making the platelet surface less sticky. stimulating the release of heparin.
interfering with the synthesis of prostaglandins
