studentparamedics: Factor IName : FibrinogenSource : LiverPathway : Both extrinsic and intrinsicActivator : ThrombinActions : When fibrinogen is converted into fibrin by thrombin, it forms long strands that compose the mesh network for clot formation.Factor IIName : ProthrombinSource : LiverPathway : Both extrinsic and intrinsicActivator : Prothrombin activatorActions : Prothrombin is converted into thrombin which then activated fibrinogen into fibrin.Factor IIIName : Thromboplastin / Tissue factorSource : Platelets (intrinsic) and damaged endothelium (cells) lining the blood vessel (extrinsic).Pathway : Both extrinsic and intrinsicActivator : Injury to blood vesselAction : Activates factor VII (VIIa).Factor IVName : CalciumSource : Bone and absorption from food in gastrointestinal tractPathway : Both extrinsic and intrinsicAction : Works with many clotting factors for activation of the other clotting factors. These are called calcium-dependent steps.Factor VName : Proaccerin / Labile factor / Ac-globulin (Ac-G)Source : Liver and plateletsPathway : Both extrinsic and intrinsicActivator : ThrombinAction : Works with Factor X to activate prothrombin (prothrombin activator).Factor VIIName : Proconvertin / Serum prothrombin conversion accelerator (SPCA) / stable factorSource : LiverPathway : ExtrinsicActivator : Factor III (tissue factor)Actions : Activates Factor X which works with other factors to convert prothrombin into thrombin.Factor VIIIName : Anti-hemoplytic factor / Antihemophilic factor (AHF) or globulin (AHG) / antihemophilic factor ASource : Endothelium lining blood vessel and platelets (plug)Pathway : IntrinsicActivator : ThrombinActions : Works with Factor IX and calcium to activate Factor X.Deficiency : Hemophilia AFactor IXName : Christmas factor / Plasma thromboplastin component (PTC) / Antihemophilic factor BSource : LiverPathway : IntrinsicActivator : Factor XI and calciumActions : Works with Factor VIII and calcium to activate Factor X.Deficiency : Hemophilia BFactor XName : Stuart Prower factor / Stuart factorSource : LiverPathway : Extrinsic and intrinsicActivator : Factor VII (extrinsic) / Factor IX + Factor VIII + calcium (intrinsic)Actions : Works with platelet phospholipids to convert prothrombin into thrombin. This reaction is made faster by activated Factor V.Factor XIName : Plasma thromboplastin antecedent (PTA) / antihemophilic factor CSource : LiverPathway : IntrinsicActivator : Factor XII + prekallikrein and kininogenActions : Works with calcium to activate Factor IX.Deficiency : Hemophilia CFactor XIIName : Hageman factorSource : LiverPathway : IntrinsicActivator : Contact with collagen in the torn wall of blood vesselsActions : Works with prekallikrein and kininogen to activate Factor XI. Also activates plasmin which degrades clots.Factor XIIIName : Fibrin stabilizing factorSource : LiverActivator : Thrombin and calciumActions : Stabilizes the fibrin mesh network of a blood clot by helping fibrin strands to link to each other. Therefore it also helps to prevent fibrin breakdown (fibrinolysis).PrekallikreinSource : LiverPathway : IntrinsicActions : Works with kininogen and Factor XII to activate Factor XI.KininogenSource : LiverPathway : IntrinsicActions : Works with prekallikrein and Factor XII to activate Factor XI. -- source link
