Weblation cascade. The end result of this cascade is the activation of thrombin, a critical enzyme. Thrombin serves two pivotal functions in hemostasis: (1) it converts soluble fibrinogen to an insoluble fibrin polymer that forms the matrix of the clot; and (2) it induces more platelet recruitment and activa-tion.
