Breathing And Exchange Of Gases Ques 1
1. Listed below are four respiratory capacities (iiv) and four jumbled respiratory volumes of a normal human adult:
[2010]
$ \begin{array}{ll} \begin{array}{l} \text { Respiratory } \\ \text { capacities } \end{array} & \begin{array}{l} \text { Respiratory } \\ \text { volumes } \end{array} \\ \text { (i) Residual volume } & 2500 \mathrm{~mL} \\ \text { (ii) Vital capacity } & 3500 \mathrm{~mL} \\ \text { (iii) Inspiratory reserve } & 1200 \mathrm{~mL} \\ \text { volume } & \\ \text { (iv) Inspiratory capacity } & 4500 \mathrm{~mL} \end{array} $
Which one of the following is the correct matching of two capacities and volumes?
(a) (ii) $2500 \mathrm{~mL} \quad $, (iii) $4500 \mathrm{~mL}$
(b) (iii) $1200 \mathrm{~mL} \quad $, (iv) $2500 \mathrm{~mL}$
(c) (iv) $3500 \mathrm{~mL} \quad $, (i) $1200 \mathrm{~mL}$
(d) (i) $4500 \mathrm{~mL} \quad $, (ii) $3500 \mathrm{~mL}$

Answer:
Correct Answer: 1.( c )
Solution:
- (c) The correct matching of respiratory capacities with their respiratory volumes are:
$ \begin{array}{|l|l|} \hline \text { Respiratory Capacities } & \begin{array}{l} \text { Respiratory } \\ \text { Volumes } \end{array} \\ \hline \text { Residual volume } & 1200 \mathrm{~mL} \\ \hline \text { Vital capacity } & 4500 \mathrm{~mL} \\ \hline \text { Inspiratory reserve volume } & 2500 \mathrm{~mL} \\ \hline \text { Inspiratory volume } & 3500 \mathrm{~mL} \\ \hline \end{array} $
