The expiratory reserve volume will be (in $; mL$)

What is the formula for $EC$ (Expiratory Capacity)?

Listed below are four respiratory capacities and four respiratory volumes of a normal human adult.

Respiratory Capacities	Respiratory Volumes
$(i)$ $RV$	$2500$ mL
(ii) $VC$	$2500$-$3000$ mL
(iii) $IRV$	$1100$-$1200$ mL
(iv) $IC$	$4500$ mL

Which one of the following is the correct matching of two capacities and volumes?

Residual air in a rabbit is found in:

The vital capacity of the lung signifies the volume of air

If Expiratory Reserve Volume $(ERV)$ is $1100 \text{ ml}$, Residual Volume $(RV)$ is $1200 \text{ ml}$ and Tidal Volume $(TV)$ is $500 \text{ ml}$, then what is the Functional Residual Capacity $(FRC)$ (in $\text{ ml}$)?
