Lab Ex. 38, 39 & 40 Blood & Blood Testing

Explore the different types of blood cells such as erythrocytes and leukocytes, including neutrophils, eosinophils, and basophils, their functions in fighting diseases, and the significance of hematocrit and differential white blood cell count in determining illnesses. Learn about the Tallqvist hemoglobin test, blood typing, antigens, antibodies, and agglutination, with a focus on the ABO system and Rh antigen. Next, delve into the role of blood vessels in the body.

Presentation Transcript

  1. Lab Ex. 38, 39 & 40 Blood & Blood Testing

  2. Blood cells

  3. Erythrocyte (RBC)

  4. Leukocyte (WBC) Have a nucleus Fight disease Neutrophils Eosinophils Basophils Monocytes/Macrophage Lymphocyte

  5. Granulocyte • This is a cell that shows granules (spots) after staining • Neutrophils • Eosinophils • Basophils

  6. Neutrophil

  7. Eosinophil

  8. Basophil

  9. Agranulocyte • This is a cell without granules • Monocytes /Macrophages • Lymphocytes

  10. Monocyte (Macrophage)

  11. Lymphocyte

  12. Platelets

  13. Hematocrit – Packed cell volume (PCV)

  14. Differential White Blood Cell Count (DIFF) • A test where the first 100 WBCs are categorized according to type. • This number can then be compared to normal %s to determine type of illness.

  15. Tallqvist hemoglobin test

  16. Blood typing

  17. Antigens • These are on the cell

  18. Antibodies

  19. Agglutination • Clumping that occurs when antibodies join to antigens

  20. ABO system B A

  21. Rh antigen D

  22. Next: Blood Vessels
