B Agranulocytes are noted for their absence of cytoplasmic granules. Monocytes are the largest white blood cells, ranging from 14 to 24 um in diameter. They make up 2 to 8 percent of all white blood cells (200-950 cells/µl). Most monocytes have kidney-shaped nuclei with a deep indentation on one side. These cells differentiate into macrophages. They attack and destroy bacteria and viruses by phagocytosis. Monocyt LM X 3520 Lymphocytes are relatively abundant in a normal blood smear making up 20 to 30 percent of all white blood cells (1500-4000 cells/ HL). They range in diameter from 5 to 17 um and are often classified as small (5-8 um), medium (9-12 ?m). and large (13-17 um). Their noclei are round and occupy the vast majority of the cell volume, leaving only a narrow rim of cytoplasm around the periphery. Lymphocytes regulate the immune response by attacking cells directly or by producing antibodies. Lymphocyte Word Origins Diapedesis is derived from Greek and means "leaping through." White blood cells can pass or "leap through the walls of blood vessels to enter surrounding tissues, where they destroy disease-causing organisms and ingest the remains of dead cells. LMX 200 In the space provided, draw and label each white blood cell type that you observe. MAKING CONNECTIONS Over-the-counter antihistamine drugs relieve the pain and discomfort of inflammation due to allergies, cold, and fever. Overuse of these drugs could prolong your symptoms, however. Speculate on a reason for this effect. (Hint: Consider the function of basophils and eosinophils.)
