Questions and Answers

Which part of the lung receives more ventilation due to the effects of gravity?

  • Alveoli in the upper lobe
  • Alveoli near the apex
  • Alveoli in the middle
  • Alveoli at the base (correct)

    • What is the relationship between compliance and alveolar volume at the apex and base of the lung?

  • Compliance is lower at the apex and higher at the base (correct)
  • Compliance is not affected by alveolar volume
  • Compliance is the same at the apex and base
  • Compliance is higher at the apex and lower at the base

    • What is the effect of gravity on the distribution of ventilation in the lung?

  • Gravity causes more ventilation at the apex and less at the base
  • Gravity causes more ventilation at the base and less at the apex (correct)
  • Gravity causes uniform distribution of ventilation
  • Gravity has no effect on ventilation
