What is Blood Clotting?? When blood vessels are cut or damaged, the loss of blood from the system must be stopped before shock and possible death occur. This is accomplished by solidification of the blood, a process called coagulation or clotting. Coagulation is a complex process by which blood forms clots. It is an important part of homeostasis (the cessation of blood loss from a damaged vessel), wherein a damaged blood vessel wall is covered by a platelet and fibrin-containing clot to stop bleeding and begin repair of the damaged vessel. Disorders of coagulation can lead to an increased risk of bleeding (hemorrhage) or obstructive clotting (thrombosis).

The process of blood clotting??? Bleeding is useful because it carries germs away from the wound, but it must not go on for too long. To prevent serious loss of blood and the entry of more germs, the wound is naturally plugged by the blood clotting. The production of a blood clot is complicated. First the nearest blood capillaries start dilating ( = increasing in diameter) and become leaky . The blood flow to the area increases for about 2 - 6 minutes (bleeding time) so that an increasing number of special white blood cells called phagocytes are transported to the wound. These pass into the tissues around the wound and destroy the germs. Pus , the yellow substance that collects at wounds, is a mixture of these phagocytes tissue fluid and the germs. If unwanted blood clots do form in the body we have very serious problems. For example, if there is "hardening of the arteries" (atherosclerosis ), a blood clot (called a thrombus ) may form on the inner surface of a blood vessel. If this clot breaks free and circulates in the blood it is known as an embolus . A thrombus or an embolus can result in a blocked blood vessel and no blood getting through to some important organ such as the heart
