That is when the blood vessels constrict themselves and become narrower. The purpose of this narrowing is to slow the blood flow down to the injured area. The second action the body takes after vasoconstriction is to form a plug made from platelets. Platelets in the blood stick together to form a plug. If the plug begins to work to prevent additional blood loss, clot formation starts and that is when At least 12 substances called clotting factors or tissue factors take part in a cascade of chemical reactions that eventually create a mesh of fibrin within the blood. Each of the clotting factors has a very specific function. Prothrombin, thrombin, and fibrinogen are the main factors involved in the outcome of the coagulation cascade.
