Presentation Transcript

  1. Blood

  2. Components of Blood • Whole blood • RBCs • WBCs • Platelets: cell fragments that aid in clotting • Plasma • 90% water (allows materials to dissolve) • Amino acids, glucose, hormones, vitamins, salts, waste • Concentrations allows diffusion in/out of blood stream

  4. Red Blood Cells • Produced from stem cells in bone marrow • Lose nucleus as they mature • Transport O2 to cells; remove CO2 • O2 binds to hemoglobin proteins • Dead cells filtered by liver & spleen

  5. Sickle Cell Normal

  6. ABO Blood Groups • Proteins on blood cells determined blood type • Antigen (markers) • proteins on cell’s surface that identify cells as foreign or natural • Antibodies: • proteins from WBCs to attack invaders • Float freely in plasma

  7. Group A blood • A antigens on the surface of your RBCs • B antibodies in your blood plasma

  8. Group B blood • B antigens on the surface of your RBCs • A antibodies in your blood plasma

  9. Group AB blood • A and B antigens on the surface of your RBCs • no A or B antibodies at all in your blood plasma

  10. Group O blood • No A or B antigens on the surface of your RBCs • both A and B antibodies in your blood plasma

  11. Rh Factors • Rh+ • Protein found in blood • Can receive Rh+ or Rh- blood • Rh- • Lack protein in blood • Only receive Rh- blood

  12. 1) Can this work? • Acceptor O- • Donor • AB-

  13. 2) Can this work? • Acceptor A+ • Donor • A-

  14. 3) Can this work? • Acceptor AB- • Donor • B-

  15. 1) Can this work? • Acceptor O- • Donor • AB- No! The AB antibodies attack the donors blood. Blood type O can only receive Blood type O.

  16. 2) Can this work? • Acceptor A+ • Donor • A- Yes! There are no Rh antigens on the donors blood cells.

  17. 3) Can this work? • Acceptor AB- • Donor • B- Yes! The AB patients can receive any blood type. And, both people do not have Rh antibodies.

  18. White Blood Cells • Remove foreign invaders & dead cells • Able to move through body tissue

  19. Platelets • Form clots when bleeding • Proteins form a web to trap cells & platelets
