What is Inspiratory Capacity (IC)?

Options

  1. ATotal volume of air a person can expire after a normal inspiration
  2. BTotal volume of air a person can inspire after a normal expiration
  3. CVolume of air remaining in the lungs after a normal expiration
  4. DVolume of air that will remain in the lungs after a forceful expiration

Correct answer

B. Total volume of air a person can inspire after a normal expiration

Step-by-step solution

Inspiratory Capacity (IC) is the total volume of air a person can inspire after a normal expiration, which includes tidal volume and inspiratory reserve volume (TV+IRV). Residual Volume (RV): Volume of air remaining in the lungs even after a forcible expiration. This averages 1100 mL to 1200 mL. By adding up a few respiratory volumes described above, one can derive various pulmonary capacities, which can be used in clinical diagnosis.
