Blood—complex transport medium that performs vital pickup and delivery services for the body. Blood—keystone of body’s heat-regulating mechanism. Whenever we cut ourselves, our blood hardens and a scab forms. This process is called blood clotting, or coagulation. Sometimes, a clot of blood can occur within a blood vessel, forming a ‘plug – Clinical Laboratory Tips for Improving Heelstick Collection Technique Hemolysis Destruction of red blood cells releases hemoglobin and other substances such as potassium into the surrounding 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 .
