  • There are several reasons why blood does not clot when present in the circulatory system
  • Heparin prevents blood from clotting in arteries.
  • The cells that line the inside of blood arteries have a smooth surface. Blood begins to clot in contact with a rough surface. Therefore, this prohibits that.
  • Endothelium's glycocalyx layer repels clotting agents and platelets, preventing clotting.
  • Anticoagulant thrombomodulin is a protein that binds to and inactivates clotting factors V and VIII.
  • Blood clot without any injury
  • A blood clot may develop in an artery or vein without injury.
  • These clots are harmful because they may obstruct blood flow.
  • They are particularly harmful if fragments reach the brain or lungs.
  • Blood-brain barrier
  • The blood-brain barrier is a selective membrane formed of endothelial cells of the capillary wall that prevents any solute from passing through.
  • The comparatively smooth and very flexible capillary walls prevent the formation of clots.
  • Even though a blood clot is migrating, it is not permitted to cross the blood-brain barrier.
