Course Learning Outcomes
  1. Relate anatomical structures of the respiratory and renal systems to their functions.
  2. Discuss the processes of ventilation, the diffusion of pulmonary gases, and measurements made to determine the effectiveness of ventilation.
  3. Explain the process of circulation and measurements made to determine the effectiveness of the heart as a pump.
  4. Discuss oxygen and carbon dioxide transport, and analyze acid-base balance.
  5. Describe how ventilation/perfusion relationships affect gas exchange.
  6. Describe how ventilation is controlled.
  7. Describe the effects of aging, exercise, and altitude on the cardiopulmonary system.
  8. Apply anatomic and physiologic principles to common clinical situations.
  9. Use graphs and nomograms in the description of physiology literature.
