Important component that helps in clotting of the blood is called ____.

  • A.Haemoglobin
  • B.Platelets
  • C.Serum
  • D.Plasma

Answer: B

Platelets are the component that starts blood clotting.

They clump at the site of injury and release thromboplastin, which converts prothrombin to thrombin; thrombin then turns soluble fibrinogen into the insoluble fibrin mesh that traps blood cells and seals the wound.
