Which one of the following respiratory volumes of human lung is the lowest?

Approximate values of human lung volumes are: Tidal volume ≈ 500 mL (air moved in/out in quiet breathing), Expiratory reserve volume ≈ 1100–1200 mL, Residual volume ≈ 1100–1200 mL, and Inspiratory reserve volume ≈ 2500–3000 mL (the largest). Tidal volume is clearly the smallest of these four. Hence tidal volume is the lowest.
