Biology - Breathing and Exchange of Gases Question with Solution | TestHub

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 $Q<S<P<R$.

Answer: $Q<S<P<R$.
