coagulation factors factors essential to normal blood clotting, whose absence, diminution, or excess may lead to abnormality of the clotting. Twelve factors, commonly designated by Roman numerals, have been described (IâV and VIIâXIII; VI is no longer considered to have a clotting function). (See table 6.).
Together with factor VIIa, tissue factor forms the tissue factor or extrinsic pathway of coagulation. This is opposed to the intrinsic (amplification) pathway which involves both activated factor IX and factor VIII. Both pathways lead to the activation of factor X (the common pathway) which combines with activated factor V in the presence of calcium and phospholipid to produce thrombin (thromboplastin activity).
