Answer 1

The correct option is C $\begin{array}{ccccc}\text{A}& \text{B}& \text{C}& \text{D}& \text{E}\\ q& t& p& r& s\end{array}$

Inspiratory Reserve Volume (IRV): It refers to the additional volume of air that can be inspired by a person after forcible inspiration. This averages 2500 mL to 3000 mL.

Expiratory Reserve Volume (ERV): It is the additional volume of air that a person can expire by a forcible expiration. This averages 1000 mL to 1100 mL.

Residual Volume (RV): It is the volume of air remaining in the lungs even after a forcible expiration. This averages 1100 mL to 1200 mL.

Inspiratory Capacity (IC): It is the total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume (TV + IRV). It approximates to 3000mL to 3500mL.

Vital Capacity (VC): It is the maximum volume of air a person can breathe in after a forced expiration. This includes ERV, TV and IRV. It can also be defined as the maximum volume of air a person can breathe out after a forced inspiration. It is around 4000mL to 4600mL.
