So generally speaking, we can divide the blood clot and cascade into three processes. The first two processes, or the two, the first two pathways are known as the extrinsic pathway and the intrinsic pathway. Now, the extrinsic pathway is shown in black with these black arrows and the intrinsic pathway is shown with the blue arrows. Now, notice that the black arrows ultimately converge with the blue arrows at this particular location where we designated with the star. And so actually, the intrinsic and the extrinsic pathway do converge at a single point and then they go on to form the final pathway, known as the final common pathway or simply the final pathway. So this is shown with the red arrow.
