HEMOSTASIS IN PHYSIOLOGY Hemostasis can refer to the Physiologic process whereby bleeding is halted. Stopped bleeding is commonly referred to, however, as Coagulation , but coagulation is only one type of hemostatic process. When a Blood Vessel is wounded, several steps occur to staunch the flow of Blood , namely:
Disorders of hemostasis can be roughly divided into platelet disorders, such as Idiopathic Thrombocytopenic Purpura , and disorders of coagulation, such as Hemophilia . Hemostasis may also refer to the complex interaction between vessels, platelets, coagulation factors, coagulation inhibitors and fibrinolytic proteins to maintain the blood within the vascular compartment in a fluid state. The objective of the hemostatic system is to preserve intravascular integrity by achieving a balance between hemorrhage and thrombosis. Hemostasis can be induced by ADP at the site of a mosquito bite to recruit platelets and oppose bloodfeeding; however mosquitoes have developed salivary apyrase to degrade ADP to counter this defense (Hurd, 2003). HEMOSTASIS BY HEMOSTATIC CLAMPS Hemostasis may refer to the process of manually clamping a Blood Vessel , usually with Hemostatic Clamp s, in Surgery or Dissection , to prevent bleeding from that vessel. This also may be done when an abnormal blood vessel forms, as these vessels may have thin walls and be prone to rupturing. EXTERNAL LINKS
