Question

Quizplus · Accepted Answer

Forming blood clots only in areas where they are needed but not in other areas requires a balance between pro-clotting forces and anti-clotting forces. One anti-clotting force is activated protein C. This substance dissolves old clots and prevents clots from forming where they are not needed by degrading clotting factor V. Factor V Leiden is a mutated form of factor V that is not easily degraded by activated protein C. As a result, clots that are not needed can form more easily.
