Blood coagulation or clotting is the mechanism to prevent excessive loss of blood from the body.
Reddish brown scum formed at the site of a cut is due to clot formed mainly of a network of threads called fibrins in which dead and damaged formed elements of blood are trapped.
Fibrins are formed by the conversion of inactive fibrinogens in the plasma by the enzyme thrombin.
Thrombins are formed from another inactive substance present in the plasma called prothrombin by an enzyme complex known as thrombokinase.
Calcium ions play a very important role in clotting.
