Arrange the following in order of increasing volume (P) Residual volume (Q) Tidal volume (R) Inspiratory reserve volume (S) Expiratory reserve volume

Options

  1. AR < S < P < Q .
  2. BQ < S < P < R .
  3. CP < Q < R < S .
  4. DS < R < Q < P .

Correct answer

B. Q < S < P < R .

Step-by-step solution

The typical values of respiratory volumes for a healthy adult human are: Tidal volume (Q) = 500 mL Expiratory reserve volume (S) = 1000 to 1100 mL Residual volume (P) = 1100 to 1200 mL Inspiratory reserve volume (R) = 2500 to 3000 mL Arranging them in increasing order of volume, we get Q Answer: Q < S < P < R .
