    Study Notes

    Platelet Production and Destruction

    • Platelets are produced in the bone marrow through the process of thrombopoiesis.
    • Old or damaged platelets are destroyed by the spleen.

    Platelet Count

    • The approximate number of platelets in 1 mm of blood is 200,000 to 400,000.

    Blood Disorders

    • The condition where the number of red blood cells (RBCs) is more than normal is called polycythemia.

    Blood Clotting

    • The protein that helps in blood-clotting with the help of clotting factors is fibrinogen.
    • Fibrinogen is converted to fibrin, which forms a mesh that traps blood cells and platelets, creating a blood clot.

    Blood Clotting Disorders

    • If the process of blood-clotting delays due to the absence of blood-clotting chemicals, uncontrolled bleeding may occur.
