  4. Colorized SEM of Red Blood Cells (red), platelets (green) and White Blood Cells (purple)

  5. Blood Smear from normal and hypochromic microcytic anemia patients

  6. Blood Smear from normal and hyperchromic macrocytic anemia patients Macrocytic Hyperchromic Anemia Normal

  7. Sickle Cell Anemia (arrow = sickle cell)

  8. Colorized SEM of Sickle Cell RBCs (green)

  9. Erythropoiesis – Red Blood Cell Development Basophilic Polychromatophilic Erythroblasts Erythroblasts Normoblast Reticulocyte

  10. Bone Marrow Smear with developing red blood cells Black arrow = basophilic erythroblast Green arrow = polychromato-philic erythroblasts

  11. Bone Marrow Smear with Megakaryocyte forming platelets (P)

  12. Blood Smear with platelets (a) – inset high mag with hyalomere and granulomere

  13. TEM of a Platelet

  14. Colorized SEM of Red Blood Cells (red), platelets (green) and White Blood Cells (yellow)

  16. Blood Smear with a Neutrophil (Polymorphonuclear Leukocyte)

  17. Blood Smear with an Eosinophil (bilobed nucleus + red granules)

  18. Blood Smear with a Basophil (irregular nucleus + dark purple granules)

  19. Diagram of Granulopoiesis White Blood Cell Development
