  3. Blood • FUNCTIONS • TRANSPORT • GLUCOSE, AMINO ACIDS, FATS, O2/CO2,HORMONES • COAGULATION • TEMPERATURE REGULATION • ANTI-BACTERIAL ACTION • PHYSIOLOGICAL ACTIVITY • HORMONE TRANSPORT • BUFFER

  4. Blood – RBC’s

  5. Blood – RBC’s • Transport : • O2 • CO2 H2O + CO2 < H2CO3> HCO3- + H+

  6. Blood – RBC’s

  7. Blood – RBC’s • What can change the production of RBC’s? • How long to RBC’s live?

  8. Blood – RBC’s CLINICAL: ANEMIA http://kidshealth.org/parent/medical/heart/anemia.html

  9. Blood – WBC’s • FUNCTIONS: • CHEMOTAXIS • DIAPEDESIS • PHAGOCYTOSIS • DEFENSINS • ANTIBODIES

  10. Blood – WBC’s NEUTROPHILS: Most abundant 50-70%; FUNCTION: phagocytosis

  11. Blood – WBC’s • EOSINOPHILS: 2-4% of WBC's; • FUNCTION: allergies, stress diseases, parasites

  12. Blood – WBC’s • BASOPHILS: 0.5% of WBC'S; • FUNCTION: liberate heparin, histamines.

  13. Blood – WBC’s • LYMPHOCYTES: 30% of WBC'S; • FUNCTION: immune responses and memory.

  14. Blood – WBC’s MONOCYTES: 3-8% of WBC's; FUNCTION: phagocytosis.

  15. Blood • PLATELETS (THROMBOCYTES) • STRUCTURE • LIFE SPAN • COAGULATION • CLINICAL - HEMOPHILIA

  16. Blood • PLASMA: • (NONLIVING MATRIX) • 3 liters • 90-93% water • maintains constant blood volume
