The volume of air remaining in the lungs after a normal expiration is known as ......

How much amount of air can be inspired or expired during normal breathing (in $; L$)?

Define the following terms:
$(a)$ Tidal volume
$(b)$ Residual volume
$(c)$ Asthma

The maximum volume of air a person can breathe in after a forced expiration is $:-$

If the respiratory rate of $A$ is $35$ breaths/min and tidal volume is $185 \, cc/breath$, and for $B$ it is $25$ breaths/min and tidal volume is $259 \, cc/breath$, then:

Listed below are four respiratory capacities $(i-iv)$ and four jumbled respiratory volumes of a normal human adult. Which one of the following is the correct matching of two capacities and volumes?

Respiratory capacities	Respiratory volumes
$(i)$ Residual volume	$2500 \; mL$
$(ii)$ Vital capacity	$3500 \; mL$
$(iii)$ Inspiratory reserve volume	$1200 \; mL$
$(iv)$ Inspiratory capacity	$4500 \; mL$
