Question

Quizplus · Accepted Answer

The correct sequence for the events of coagulation starts with the activation of factor XII (3), which is part of the intrinsic pathway initiation. This leads to the formation of prothrombinase (4), which then converts prothrombin into thrombin (1). Finally, thrombin converts fibrinogen into fibrin (2), forming the clot.
