3)You would also have to watch out for: </span><span><span>Granulocytes – cells which contain granules which contain chemicals that are used to kill bacteria and viruses </span><span>Lymphocytes- cells which attack most of the bacterial and viral infections in our bodies</span><span>Monocytes - cells which become macrophages, large cells that engulf harmful particles in our bodies</span></span>
