The worldwide incidence of hemophilia A, caused by a deficiency in factor 8, is approximately 1 in every 5,000 male births. The complex series of events that comprise the blood clotting process relies on the swift and efficient function of numerous proteins, including understanding what is the mechanism of action of factor 8.

While the intrinsic coagulation pathway starts with Factor XII, the proteolytic enzyme primarily responsible for activating Factor VIII is thrombin. This activation is a vital step in amplifying the clotting signal and leading to the formation of a stable blood clot.

Blood coagulation is a complex and vital physiological process involving a precise sequence of events. A key part of understanding this mechanism is answering the question: **What is the function of factor 8 and 9?** These proteins are essential for forming a stable blood clot to prevent excessive bleeding.

Hemophilia is a rare inherited bleeding disorder in which the blood does not clot properly. For individuals with this condition, a specific laboratory test will consistently yield an abnormal, prolonged result, which is a key diagnostic indicator for understanding **which is prolonged in hemophilia**.

Hemostasis, the process of stopping bleeding, begins with a cascade of events. This crucial mechanism is what answers the question: **What are the two pathways that initiate clotting?** They are vital for preventing excessive blood loss after an injury.
