Common to both the intrinsic and the extrinsic pathway is
A) factor XII.
B) factor VII.
C) factor X.
D) subendothelial collagen.

Question

Quizplus · Accepted Answer

When blood is exposed to subendothelial collagen or is "injured," factor XII is activated,which initiates coagulation via the intrinsic pathway.In the extrinsic pathway,tissue injury precipitates release of a substance known as tissue factor,which activates factor VII.Factor VII is key in initiating blood coagulation,and the two pathways intersect at the activation of factor X.Both coagulation pathways illustrate a final common pathway of clot formation,retraction,and fibrinolysis.
