Figure 1A: A diagram illustrating the surface bound complex enzymes of the “intrinsic” and “extrinsic” coagulation pathways. The surface bound complex of the intrinsic pathway is outlined by a dashed line. The amplification by thrombin feedback activations of fV, fVIII, fVII and fXI are also illustrated.

Figure 1B: Coagulation system regulation by the stoichiometric (AT and TFPI) inhibitors which down-regulate the system by binding the serine proteases and the dynamic APC system, which causes proteolytic inactivation the cofactors (fVa and fVIIIa).
