Although this is not how coagulation works in vivo (it cannot be, as it does not explain why haemophilia is a bleeding disorder, or why factor XII deficiency is not associated with a bleeding tendency), it is still ... WebCoagulation can be initiated by two different pathways; the intrinsic pathway secondary to vascular endothelium damage and sub-endothelial collagen exposure and the TF-dependent extrinsic pathway. However, the initiation of either pathway results in the activation of FX of the cascade, leading to the formation of a fibrin clot [27].
