The TF:FVIIa complex of the extrinsic pathway initiates blood coagulation by activating both FX and FIX. WebAs each step of clotting occurs, it stimulates the release of more clotting substances. This accelerates the processes of clotting and sealing off the damaged area. Clotting is contained in a local area based on the tightly controlled availability of clotting proteins.
