Question

Ravi injured his knee while playing and it was bleeding. After some time, he noticed that the bleeding had stopped and a dark red clot had plugged the wound. Which type of cells help in blood clotting?

A.

Platelets

B.

Lymphocytes

C.

Eosinophils

D.

Red blood corpuscles

Correct option is A

​The correct answer is: (A). Platelets
  • Platelets, also known as thrombocytes, are small cell fragments in the blood that play a crucial role in blood clotting (hemostasis).
  • When there is an injury to a blood vessel, platelets quickly gather at the site of the wound, sticking together to form a plug.
  • They also release chemicals that activate other clotting factors, leading to the formation of a blood clot and helping to stop the bleeding.​
Information Booster:
  • Lymphocytes:Lymphocytes are a type of white blood cell involved in the immune response.
  • Eosinophils:Involved in allergic reactions and defense against parasites.
  • Red Blood Corpuscles (RBCs):primary function is to transport oxygen from the lungs to the tissues and carry carbon dioxide back to the lungs for exhalation.​
