Question

The intrinsic pathway of coagulation is activated by the
A) sticking of platelets to each other.
B) activation of Factor XII by platelet factors.
C) release of tissue factor (Factor III) by damaged endothelium.
D) release of heparin from the liver.
E) conversion of prothrombin to thrombin.

Accepted Answer

The intrinsic pathway of coagulation is activated by the activation of Factor XII by platelet factors, as well as other factors like Factor XI and prekallikrein. This leads to a cascade of reactions ultimately leading to the formation of a fibrin clot.
