MECHANISM OF BLOOD CLOTTING

The process of blood clotting is referred to as coagulation. Ounce a person is injured; the arteries or veins of the injured area are destroyed. This situated triggers the production of platelets, which starts to form clumps around the injured area. The platelets also release messengers into the blood that helps in the constriction of the blood vessels of the injured area so as to reduce the rate of bleeding. Also plasma based clotting factors called fibrinogen are produced. The fibrinogen is then converted into fiber like materials called fibrin. The platelets together with the fibrin form a network of mesh like structure resulting in the formation of clot around the injured area.
