HEMOSTASIS
DEFINITION;hemostasis is the a process to prevent bleeding
Stages of hemostasis
Vaso constriction
Platelet plug formation
Coagulation of blood
Factors involved in blood clotting
Factor I Fibrinogen
Factor II Prothrombin
Factor III Thromboplastin
Factor IV Calcium
Factor V Labile factor (proaccelerin)
Factor VI Presence has not been proved
Factor VII Stable factor or Proconvertin or
serum prothrombin conversion
accelerator (SPCA)
, Factor VIII Antihemophilic factor A
(Antihemophilic globulin
Factor IX Antihemophilic factor B or Christmas
factor (PTC)
Factor X Stuart prower factor (Auto
Prothrombin III)
Factor XI Plasma thromboplastin antecedent
(PTA)
Factor XII Hageman factor (Surface or glass
contact factor)
Fibrino stabilizing factor (Laki-Lorand
Factor XIII
factor)
Stages of Coagulation
Stage 1 Inactive procoagulants become active and finally there is formation of
prothrombin activator
Stage 2 Conversion of prothrombin into thrombin
Stage 3 Conversion of fibrinogen into fibrin
