  4. Review the anatomy of the lungs, airways, and vasculature.
  5. Explain the role of diaphragm and intercostal muscles in breathing mechanics.
  6. Diagram the normal blood flow through the heart.
  7. Differentiate atrial and ventricular anatomy 
  8. Describe the anatomical relationship of the pleural and pericardial cavities.
  9. Describe the anatomical relationship of the heart to adjacent thoracic structures.
  10. Describe the foramen ovale and ductus arteriosus and changes that occur at birth.
  11. Distinguish the anatomical features of each cardiac chamber and valve.
  12. Diagram the normal coronary artery and venous distribution pattern, including types of dominance patterns.
  13. Describe the cardiac conduction system and its blood supply.
  14. Review the neural input to the heart.
  15. Recognize the origin of heart sounds
Pulmonary Mechanics
  1. Describe the mechanical forces that control lung volume and chest wall.
  2. Differentiate mechanisms of airway obstruction.
  3. Identify methods for measuring pulmonary function.
Pulmonary Circulation
  1. Describe the pathogenesis of primary pulmonary hypertension
  2. Identify cardiovascular consequences of pulmonary hypertension.
  3. Differentiate primary pulmonary hypertension from secondary pulmonary hypertension.
Cardiovascular Physiology
  1. Delineate the etiologies explain the pathogenesis of acute cardiogenic shock.
  2. Recognize common clinical presentations and treatment regimens for acute cardiogenic shock.
  3. Apply principles of cardiac physiology to recognize the value of cardiac catheterization (Swan-Ganz catheterization).

  2. Diagram the relationships between venous and arterial pressure
  3. Diagram the venous return curve, cardiac function curve, vascular function curve, and pressure-volume loops.
  4. Describe how changes in contractility, venous pressure, arterial pressure, compliance, sympathetic activity, blood volume, and peripheral resistance affect the cardiac function curve, vascular function curve, and pressure-volume loop.
  5. Analyze the effect of complex changes such as exercise to overall cardiac function.
Alveolar Ventilation and Gas Transport
