  • 3. How is hemoglobin important in the transport of oxygen in our bodies? • It gives us oxygen and takes away carbon dioxide
  • 4. Why is the transport of oxygen by hemoglobin a real-life example of chemical bonding • Cause the oxygen and the carbon dioxide mix
  • 5. How is hemoglobin related to a successful climb to the top of Mt. Everest • It gives you a bunch of oxygen when they go higher on the mountain
  • 6. We learned about pH in our last unit on acid and bases. What does pH have to do with the transport of oxygen by hemoglobin • It is like adding more red cells to the blood flow.

  • 10. What are the medical uses of blood doping • Another similar use of medical technology is called blood doping, either by blood transfusion or use of the hormone erythropoietin (EPO).
  • 11. Why is blood doping used in sports • Increase peoples endurance for running and breathing
  • 12. Provide 1 example of blood doping used in sport • Running for cross country.
  • 13. Provide a 2nd example of blood doping used in sport • Also playing soccer because you need to run back and forth
  • 14. What are the side effects of blood doping? • The simple act of increasing the number of RBC's in the blood stream makes blood thicker and chance for heart attack.
