The volume of air remaining in the lungs and the dead space even after maximum expiration is ----------ml.

Options

  1. A500
  2. B1000-1100
  3. C1100-1200
  4. D2000-3000

Correct answer

C. 1100-1200

Step-by-step solution

The volume of air remaining in the lungs and the respiratory passages (dead space) even after a forceful or maximum expiration is called the Residual Volume (RV). The average value of Residual Volume in a healthy human adult is 1100 mL to 1200 mL. Other respiratory volumes are: Tidal Volume (TV) 500 mL Expiratory Reserve Volume (ERV) 1000 to 1100 mL Inspiratory Reserve Volume (IRV) 2500 to 3000 mL Answer: 1100-1200
