Questions and Answers

In which region of the airway does laminar flow predominate?

  • Smaller bronchioles (correct)
  • Alveoli
  • Medium bronchioles
  • Trachea

    • How does turbulent flow affect airway resistance?

  • Minimizes artificial airway curvature
  • Increases resistance temperature
  • Decreases resistance
  • Adds friction and increases resistance (correct)

    • What is the main function of the muscles of breathing?

  • Relax to decrease resistance
  • Contract to increase diameter
  • Promote turbulent flow
  • Maintain intrathoracic pressure (correct)
