If expiratory reserve volume is $1100 \ ml$,residual volume is $1200 \ ml$,and tidal volume is $500 \ ml$,what shall be the functional residual capacity (in $ml$)?

Where is the residual air mostly found?

$500\,ml$ respiratory volume in a normal adult human is related to:

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 $\text{ ml}$)?

Match Column-$I$ with Column-$II$ and select the correct option:

Column-$I$	Column-$II$
$a.$ Tidal Volume	$i.$ $2500$ to $3000 \, mL$ of air
$b.$ Inspiratory Reserve Volume	$ii.$ $1000 \, mL$ of air
$c.$ Expiratory Reserve Volume	$iii.$ $500 \, mL$ of air
$d.$ Residual Volume	$iv.$ $3400$ to $4800 \, mL$ of air
$e.$ Vital Capacity	$v.$ $1200 \, mL$ of air

The volume of air that remains in the lungs after a normal expiration is known as:
