So Thrombin not only activates platelets and calls upon platelets, it also forms Fibrin and it activates factor 13 that is needed to form the covalent bonds between many of these adjacent Fibrin that lie along that rupture. So we see that the final pathway consists of the following. When factor ten is activated by either the extrinsic or the intrinsic pathway, it combines with factor five to form a dimer complex we call prothrombinase. And it's prothrombinase, which is also a protease enzyme that activates prothrombin in our blood and turns it into the active With factor ten. It activates factor eight to combine with factor nine, as well as this VWF, which stands for Von Willebrand Factor, which is another protein that is needed to basically stabilize factor eight. It activates the complex that goes on to activate more of ten to form this complex.
