Antihemophilic factor
Antihemophilic Factor
Antihemophilic factor (pronunciation: an-tee-hee-muh-FIL-ik FAK-tur), also known as Factor VIII (FVIII), is a protein that plays a crucial role in the process of blood clotting. It is one of the clotting factors that work together to ensure that blood clots properly when a blood vessel is injured.
Etymology
The term "antihemophilic factor" is derived from the Greek words "anti" (against), "haima" (blood), and "philia" (love). This is because the factor acts against hemophilia, a condition where the blood does not clot properly, leading to excessive bleeding.
Function
Antihemophilic factor is produced in the liver and released into the bloodstream. It is activated when there is an injury that causes bleeding. The activated antihemophilic factor then interacts with other clotting factors, such as Factor IX and Factor X, to form a clot and stop the bleeding.
