b. Inspiratory Reserve volume 2 1100-1200 mL
c. Expiratory Reserve volume 3 500-550 mL
d. Residual volume 4 1000-1100 mL

a4,b1,c2,d3

Solution:

a) Tidal volume is the volume of air displaced between normal inspiration and expiration without an extra effort. In a healthy human, it is approximately 500-550 mL.
b) Inspiratory reserve volume (IRV) is the maximal amount of air that can be inhaled into the lungs by after normal inspiration. In a healthy human, it is approximately 2500-3000 mL.
c) Expiratory reserve volume (ERV) is the maximal amount of air that can be expelled out from the lungs after normal expiration. In a healthy human, it is approximately 1000-1100 mL.
d) Residual volume (RV) is the volume of air that remains in the lungs after the most forcible expiration. In a healthy human, it is approximately 1100-1200 mL.
Thus, the correct answer is option D.
