The extrinsic and intrinsic pathways join at the common pathway through the activation of which clotting substance produced by the liver?

Question

Quizplus · Accepted Answer

The extrinsic and intrinsic pathways both activate Factor X, which then joins the common pathway to ultimately form a clot. Fibrinogen is not produced by the liver, but rather by the liver and other cells in the body. Calcium and vitamin K also play important roles in the clotting process, but they are not the clotting substance produced by the liver that joins the two pathways. Albumin is not involved in the clotting process at all.
