#coagulation_factor__coagulationfactor__clottingfactor  any of the factors in the blood whose actions are essential for blood coagulation
  supertype:  #plasma_protein  any of the proteins in blood plasma
  subtype:  #fibrinogen__factor_I  a protein present in blood plasma; converts to fibrin when blood clots
  subtype:  #prothrombin__factorii  a protein in blood plasma that is the inactive precursor of thrombin
  subtype:  #thromboplastin__thrombokinase__factor_III  an enzyme liberated from blood platelets that converts prothrombin into thrombin as blood starts to clot
  subtype:  #calcium_ion__calciumion__factor_IV  ion of calcium; a factor in the clotting of blood
  subtype:  #proaccelerin__prothrombin_accelerator__prothrombinaccelerator__accelerator_factor__acceleratorfactor__factor_V  a coagulation factor
  subtype:  #proconvertin__cothromboplastin__stable_factor__factor_VII  a coagulation factor formed in the kidney under the influence of vitamin K
  subtype:  #antihemophilic_factor__antihaemophilic_factor__antihaemophilicfactor__antihemophilic_globulin__antihaemophilic_globulin__antihaemophilicglobulin__factor_VIII__Hemofil  a coagulation factor (trade name Hemofil) whose absence is associated with hemophilia A
  subtype:  #Christmas_factor__factor_IX  coagulation factor whose absence is associated with hemophilia B
  subtype:  #prothrombinase__factor_X  coagulation factor that is converted to an enzyme that converts prothrombin to thrombin in a reaction that depends on calcium ions and other coagulation factors
  subtype:  #plasma_thromboplastin_antecedent__factor_XI  coagulation factor whose deficiency results in a hemorrhagic tendency
  subtype:  #Hageman_factor__factor_XII  coagulation factor whose deficiency results in prolongation of clotting time of venous blood
  subtype:  #fibrinase__factorxiii  in the clotting of blood thrombin catalyzes factor XIII into its active form (fibrinase) which causes fibrin to form a stable clot
