  1. Formed elements
    45% of blood

    erythrocytes, leukocytes and thrombocytes
  2. erythrocytes
    • -most common blood cell type
    • -bioconcave shape
    • -no nulceus
    • -oxygen and carbon dioxide transport
  3. platelets (thrombocytes)
    • -involved in clotting
    • -small megakaryocyte fragments
  4. granulocytes
    granules in their cytoplasm
  5. Neutrophils
    • - 3-5 lobed nucleus
    • - granular
    • - major phagocitic WBC
    • - major bacterial infection fighter
    • - 1.5 the size of RBC
    • - 60-70% of WBC
  6. Eosinophil
    • -2 lobed nucleus
    • -granular
    • -pink-orange granules
    • -twice the size of RBC
    • -involved in immune function related to parasites and allergies
    • -2-4% of WBC
  7. Basophil
    • -S shaped nucleus
    • -granular
    • -dark staining granules
    • -twice the size of RBC
    • - 0.5-1% of WBC
    • - involved in allergic reactions & radiation exposure

    -their granules contain histamines (vasodilators) and heparin, an anticoagulant that allows the movement of other white blood cells out of the capillaries to infection sites.
  8. agranular
    lacking cytoplasmic granules
  9. lymphocytes
    • - nucleus flat on one side
    • - agranular
    • - same to 2.5 times the size of RBC
    • - 20-25% of WBC
    • - involved in viral infections & antibody-antigen reactions
  10. monocyte
    large kidney-shaped nucleus

    agranular

    2 times the size of RBC

    3-8% of WBC

    involved in chronic infections
