And so in the intrinsic pathway, what happens is as a result of the exposure of the collagen found in the extracellular environment outside that blood vessel, so basically, as a result of that cut in the blood vessel, we basically create a cascade of events. We have these activation events taking place. We have Xiaomogen Twelve activating to its enzyme Twelve, and enzyme Twelve activates Eleven into its active form. Eleven, then activates nine. Into its active form, which combines with protein Eight to basically activate the same x, the same enzyme, ten xiaomogen ten, that we have in this case. And so these two pathways basically converge to form the single pathway we commonly call the final common pathway, or simply the common pathway.
