What potential state of the blood can be caused by the formation of excessive amounts of plasmin?
Explanation
While the primary role of plasmin is to dissolve existing clots, its action is not entirely specific to fibrin. Excessive plasmin can also digest key clotting factors like fibrinogen and prothrombin, which can impair the blood's ability to clot and lead to a state of hypocoagulability.
