And to be more specific, it's factor eight that is affected as a result of hemophilia. And that's exactly why factor eight is also commonly known as the antihmophilic factor. And that's because if this antihemophilic factor is actually present and functions correctly inside our body, then that will prevent hemophilia A, also known as classic hemophilia. So factor eight is a protein that plays a crucial role in the intrinsic pathway of the blood clot and cascade. And there are two important roles, as we discussed just a moment ago. So rule number one is it actually plays an important role in actually completing the intrinsic pathway.
