Which of the following plays the major role in clotting of blood?
(a) RBC
(b) WBC
(c) Platelets
(d) none of these
Correct Answer: (c) Platelets
Explanation:
Blood does not clot inside the body due to the presence of anticoagulant heparin.
As soon as any injury takes place externally over the body, the clotting agents like thrombin, fibrinogen, vitamin K helps in the clotting of blood and prevent blood loss externally over the body.
The function of the platelets in the blood is the clotting of blood. They contain certain chemicals like heparin which help in the coagulation of blood at the site of a cut or wound.
