87diffuse intravascular coagulation — (DIC), disseminated intravascular coagulation a bleeding disorder characterized by abnormal reduction in the elements involved in blood clotting due to their use in widespread intravascular clotting. It may be caused by any of numerous disorders; …
88extrinsic pathway of coagulation — the mechanism that produces fibrin following tissue injury, beginning with formation of an activated complex between tissue factor and activated factor VII and leading to activation of factor X, which induces the reactions of the common pathway… …
89intrinsic pathway of coagulation — a sequence of reactions leading to fibrin formation, beginning with the contact activation of factor XII, followed by the sequential activation of factors XI and IX, and resulting in the activation of factor X, which in activated form initiates… …
90blood coagulation — blood clotting the process whereby blood is converted from a liquid to a solid state. The process may be initiated by contact of blood with a foreign surface (intrinsic system) or with damaged tissue (extrinsic system). These systems involve the… …
