Activation  of the blood coagulation cascade often activates, or is accompanied by the activation of other systems. This  appears to be largely the result of activating Factor XII (the Hageman  factor) - i.e. the initiation of  plasma thromboplastin.

Activation  of the blood coagulation cascade often activates, or is accompanied by the activation of other systems. This  appears to be largely the result of activating Factor XII (the Hageman  factor) which simultaneously triggers other body systems:
