http://www.emergencymedicalparamedic.com/clotting-cascade/ WebHemostasis is the physiological process by which bleeding ceases. Hemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, in which clotting factors promote the formation of a fibrin clot. Fibrinolysis is the process in which a clot is degraded in a healing vessel.

WebAgeneral scheme of the clotting cascade is shown in Figure 1. After vascular injury, clotting is initiated by the binding of plasma FVII/FVIIa to tissue factor (TF) (also known as coagulation factor III or tissue thromboplastin). The TF:FVIIa complex of the extrinsic pathway initiates blood coagulation by activating both FX and FIX. WebClotting Factors Involved in Coagulation.
