The common coagulation pathway
WebThe pathway has two entry points to begin the cascade, the "intrinsic" and "extrinsic" pathways. The common pathway begins with the activation of clotting factor X, which is … WebConversely, the extrinsic pathway is called extrinsic because it’s activated by tissue factor found extrinsically, or outside of the blood. Both pathways can become activated independently and ultimately culminate in the activation of factor X, which then proceeds to activate the rest of the coagulation cascade via the common pathway.
