What is Residual Volume (RV)?

Options

  1. AThe volume of air a person can inspire by a normal inspiration
  2. BThe volume of air a person can expire by a normal expiration
  3. CThe volume of air remaining in the lungs even after a forcible expiration
  4. DThe volume of air a person can inspire by a forceful inspiration

Correct answer

C. The volume of air remaining in the lungs even after a forcible expiration

Step-by-step solution

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. 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 inspir
