What does Total Lung Capacity include?

Options

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

Correct answer

A. Vital capacity and residual 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
