What does Vital Capacity (VC) include?

Options

  1. AResidual volume, tidal volume, and inspiratory reserve volume
  2. BResidual volume, tidal volume, and expiratory reserve volume
  3. CResidual volume, inspiratory reserve volume, and functional residual capacity
  4. DExpiratory reserve volume, tidal volume, and inspiratory reserve volume

Correct answer

D. Expiratory reserve volume, tidal volume, and inspiratory reserve volume

Step-by-step solution

Inspiratory Capacity (IC): Total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume ( TV+IRV). Expiratory Capacity (EC): Total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume (TV+ERV). Functional Residual Capacity (FRC): Volume of air that will remain in the lungs after a normal expiration. This includes ERV+RV. Vital Capacity (VC): The maximum volume of air a person can breath
