Presentation Transcript

  1. Formed Elements Erythrocytes, Leukocytes & Platelets 60 - 70% Neutrophils Never Let Monkeys Eat Bananas Lymphocytes Monocytes 1% 5-10K/μl Eosinophils 0.5 - 1% Basophils Granulocytes - Specialized membrane bound granules Phagocytes Agranulocytes - Lack granules

  2. Erythrocytes & Platelets Transport O2 & CO2 Clotting cascade

  3. Plasmodium Fibrin sheet

  4. Neutrophils Multilobed nucleus Neutral – acid or base Phagocyte: Bacteria Granules - lysozyme

  5. Barr body

  6. Hyper-segmented Pernicious anemia

  7. Lymphocytes Main functional cells of Immune system

  8. Reactive Small normal T-cells Recognize & lyse virus infected cells Cell mediated immunity B-cells Plasma cells secrete antibodies

  9. Monocyte Connective tissue macrophages Precursor cell

  10. Neutrophil & Monocyte

  11. Eosinophil Refractile granules

  12. Phagocyte: Worms Antigen-antibody complex Moderate inflammatory response
