Functional residual capacity in human is the amount of air
1 that can be filled in lungs by forceful inspiration.
2 that can be breathed out after forceful expiration.
3 that remains in the lungs after normal expiration.
4 that remains in the lungs after forceful expiration.
Explanation:
(c) This includes RV and ERV ( $2500\text{ml})$.

The structure which prevents the entry of food into the windpipe is
1 gullet
2 glottis
3 tonsil
4 epiglottis
Explanation:
(d) Epiglottis is a stiff flap like structure covering the glottis. It acts as a trapdoor to the trachea and prevents the entry of food going down to lungs.

The amount-of air remaining in the air passages and alveoli at the end of quiet respiration is called
1 tidal volume
2 inspirating reserve volume
3 inspiratory capacity
4 functional residual capacity
Explanation:
(d) Functional residual capacity (FRC) is the volume of air remaining in the lungs after a normal expiration (ERV + RV). It is about $2300\text{ml}$.
