Sudden and severe loss of blood can lead to shock and death. When blood vessels are damaged, Hemostasis (clot formation) will arrest bleeding. This process is divided into three phases.

I. Vascular phase - Cutting or damaging blood vessels leads to vascular spasm of the smooth muscle in the vessel wall. This produces a vasoconstriction which will slow or even stop blood flow. This response will last up to 30 minutes and is localized to the damaged area.

II. Platelet phase - Damaged endothelial cells lining the blood vessel release von Willebrand's Factor. This substance makes the surfaces of the endothelial cells "sticky". This condition may, by itself, be enough to close small blood vessels. In larger blood vessels, platelets begin to stick to the surfaces of endothelial cells. This effect is called Platelet Adhesion.

III. Coagulation Phase - Begins 30 seconds to several minutes after phases I and II have commenced.

When a blood vessel is cut or damaged, the injury initiates a series of reaction, which prevent the further blood loss.This type of arrest of bleeding is called Hemostasis
it occurs in 3 stages 1. vasoconstriction, 2. formation of platelet plug and coagulation of blood.
