Topic D.6: Transport of Respiratory Gases

Understandings:
  • Oxygen dissociation curves show the affinity of hemoglobin for oxygen.
  • Carbon dioxide is carried in solution and bound to hemoglobin in the blood.
  • Carbon dioxide is transformed in red blood cells into hydrogen carbonate ions.
  • The Bohr shift explains the increased release of oxygen by hemoglobin in respiring tissues.
  • Chemoreceptors are sensitive to changes in blood pH.
  • The rate of ventilation is controlled by the respiratory control centre in the medulla oblongata.
  • During exercise the rate of ventilation changes in response to the amount of CO2 in the blood.
  • Fetal hemoglobin is different from adult hemoglobin allowing the transfer of oxygen in the placenta onto the fetal hemoglobin.
Applications:
  • Consequences of high altitude for gas exchange.
  • pH of blood is regulated to stay within the narrow range of 7.35 to 7.45.
  • Causes and treatments of emphysema.
Skills:
  • Analysis of dissociation curves for hemoglobin and myoglobin.
  • Identification of pneumocytes, capillary endothelium cells and blood cells in light micrographs and electron micrographs of lung tissue.
Nature of Science:
  • Scientists have a role in informing the public—scientific research has led to a change in public perception of smoking.
