Introduction. Blood—made up of plasma and formed elements. Blood—complex transport medium that performs vital pickup and delivery services for the body. Blood—keystone of body’s heat-regulating mechanism. According to Howell Theory of blood coagulation , the change of fibrinogen into fibrin is caused by thrombin which in fluid exists as prothrombin. The conversion of prothrombin to thrombin depends on the action of thromboplasin and calcium. . Professor . Dr.Noori. Mohammed . Luaibi. HEMOSTASIS EVENTS . The . term hemostasis means prevention of blood loss. Whenever a vessel is severed or ruptured, hemostasis is achieved by several mechanisms: (. Part of ECF. Has two portions. Cellular components.
