You need to get your head around this.  Gas Exchange     The effect of exercise on heart and lungs    And here’s a great presentation to help.

  • Define partial pressure.
  • Explain the oxygen dissociation curves of adult hemoglobin, fetal hemoglobin and myoglobin.
  • Describe how carbon dioxide is carried by the blood. [Include action of carbonic anhydrase, chloride shift, and plasma proteins]
  • Explain the role of the Bohr shift in the supply of oxygen to respiring tissues.
  • Explain how and why ventilation rate varies with exercise.
  • Outline the possible causes of asthma and its effects on the gas exchange system.
  • Explain the problem of gas exchange at high altitudes and the way the body acclimatizes.
