Blood Clotting

  • Platelets are fragments of cells which are involved in blood clotting and forming scabs where the skin has been cut or punctured
  • Blood clotting prevents continued / significant blood loss from wounds
  • Scab formation seals the wound with an insoluble patch that prevents entry of microorganisms that could cause infection
  • It remains in place until new skin has grown underneath it, sealing the skin again
