    Which type of blood cells are associated with clotting–
    Question

    Which type of blood cells are associated with clotting–

    A.

    WBC

    B.

    RBC

    C.

    Platelets

    D.

    Lymphocytes

    Correct option is C


    Sol. Platelets, also called thrombocytes, are small, disc-shaped cell fragments in the blood that are essential for blood clotting. When a blood vessel is injured, platelets aggregate at the site to form a clot and stop bleeding.
    Explanation of each option:
    · (a) WBC (White Blood Cells) – These are immune cells that help fight infection but do not participate in blood clotting.
    · (b) RBC (Red Blood Cells) – They carry oxygen using hemoglobin but have no role in the coagulation process.
    · (c) Platelets – Correct answer. They release clotting factors and help form a plug at injury sites, initiating the clotting cascade.
    · (d) Lymphocytes – A subtype of WBCs involved in adaptive immunity (B-cells and T-cells), not clot formation.
