Q. What are clotting factors?

Clotting factors are substances (coenzymes, enzymes, reagents) necessary for the clotting stages to happen. Besides those triggering reagents and factors already described (platelet and tissue factors, prothrombin, thromplastinogen, fibrinogen, calcium ions), other substances participate in the blood clotting process as clotting factors like factor VIII whose deficiency causes hemophilia A or the factor IX, whose deficiency causes hemophilia B.
