Initiates blood coagulation
WebbThromboplastin acts on and accelerates the activity of Factor Xa, also known as thrombokinase, [1] aiding blood coagulation through catalyzing the conversion of prothrombin to thrombin. Thromboplastin is found in brain, lung, and other tissues and especially in blood platelets.
