BLOOD CLOTTING MECHANISM
Clotting factors in
plasma Clumped platelets Damaged cells
Activators
thromboplastin
Calcium ions, Ca2+ Vitamin K
Prothrombin (inactive
plasma protein)
Thrombin (active plasma
protein which act as enzyme)
Fibrinogen
(soluble)
Fibrin(insoluble)
Fibrin form a mesh of fibres across
the wound, sealing wound and
preventing further loss of blood
form
