  2. B. Expiratory reserve volume
  3. C. Oxygen capacity of blood
  4. D. Alveolar ventilation of lungs
  5. E. Diffusing lung capacity
Hint

Separate parameters that depend on airflow mechanics from those that depend on gas transfer across the membrane, and decide which one a thicker membrane affects directly.
