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
