Blood clotting

• Thrombosis:

  Blood clotting at the site of rupture.
• Blood clotting cascade:

  • Blood vessel wall is damaged
  • Exposing collagen fibres
  • Clotting factors are released - thromboplastin
  • Converts prothrombin to thrombin (Ca+, Vitamin K)
  • Thrombin
  • Converts fibrinogen to fibrin
  • Fibrin
  • Forms a mesh of fibres
  • Traps red blood cells
