During an injury when you are cut, what pathway of coagulation is used?

a) Intrinsic pathway
b) Extrinsic pathway
c) Common pathway
d) Secondary pathway

Answer :

Final answer:

The correct option is b) Extrinsic pathway. The extrinsic pathway of coagulation is primarily utilized during an injury when you're cut, eventually converging into the common pathway to form a stable blood clot.

Explanation:

During an injury when you're cut, the extrinsic pathway of coagulation is primarily used. This pathway is triggered by tissue damage that exposes blood to tissue factor, initiating a rapid response to stop bleeding.

The intrinsic and extrinsic pathways eventually converge into the common pathway, leading to the formation of a stable blood clot through a series of complex reactions involving various clotting factors and platelets.
