  1. Plasma
    • C.T. matrix
    • 55% total blood volume
    • 92% water
    • 7% plasma proteins
  2. Plasma proteins
    • albumin-osmotic balance
    • fibrinogen-blood clotting
    • globulins-defense (antibodies)
  3. Formed elements
    • 45% total blood volume
    • 99.9% RBC's( erythrocytes)-transport O2 and CO2
    • 0.1% WBC's(leukocytes)-defense/immunity
  4. Leukocytes
    • White blood cells
    • Never Let Monkeys Eat Banannas
    • (most --> least common)
  5. Neutrophil (granulocyte)
    • 3-7 lobed nucleus, small blue/purple granules
    • development-14 days
    • life span-6hours-few days
    • function-phagocytize bacteria
  6. Eosinophil (granulocyte)
    • bi-lobed nucleus, red granules
    • development-14 days
    • life span-8-12 days
    • function-kill parasitic worms, destroy antigen-antibody complexes
  7. Basophil (granulocyte)
    • U or S shaped nucleus, large purple granules
    • development-1-7 days
    • life span-few hours-few days
    • function-release histamine & other mediators of inflammation
  8. Lymphocyte (agranulocyte)
    • smallest WBC, spherical nucleus w/ light blue cytoplasm
    • development-days-weeks
    • life span-hours-years
    • function-mount immune response via direct cell atk or antibodies
  9. Monocyte (agranulocyte)
    • large U (kidney) shaped nucleus, grey-blue cytoplasm
    • development-2-3 days
    • life span-months
    • function-phagocytosis. develop into macrophages in tissues
  10. Platelets
    • cell fragments
    • development-4-5 days
    • life span-5-10 days
    • function-seal small tears in blood vessels, blood clotting
  11. Hematocrit (packed cell volume)
    • formed elements/total blood volume
    • determines % RBC's in blood
    • male-40-54%
    • female-37-47%
  12. Agglutinogens (antigens)
    specific glycoproteins on the outer surface of the RBC plasma membrane.
  13. Agglutinins (antibodies)
    plasma proteins that accompany and react with RBC antigens, causing them to be clumped and eventually hemolyzed
  14. Blood typing
    -on slide, reaction (clumping) means you have that antigen.
    you make antibodies for the anitgens you don't have
