And the protein factor eleven, when it's activated it goes on to activate that same protein factor nine that we dealt with in the extrinsic pathway. Now once nine is activated, once again it goes on and activates ten. So we see the underlying reason why we have these two different processes is so that we have more pathways by which we can form more of number ten. Because once again, it's the number ten that will combine with the factor five to form a dimer complex that will go on and ultimately lead to the formation of our blood clot. So we have these two pathways, the extrinsic and the intrinsic that eventually create many of these separate pathways that amplify the number of these complexes that we form. And once they converge this complex goes on and forms our blood clots as we'll see in just a moment.
