WebApr 5, 2016 · Both the intrinsic and extrinsic pathways lead to factor 10, which is the start of the common pathway. The two key players in the common pathway are thrombin and fibrin. Fibrin is the most important part of the clotting cascade because fibrin is what traps the platelets, and is therefore clotting factor number 1. WebThe intrinsic pathway originally described by these models does not appear to be essential for in vivo hemostasis but may play a role in pathologic thrombosis. The waterfall/cascade models' lack of cellular elements sets the stage for the cell-based model of coagulation.
