Which of the following respiratory volumes and capacities has the lowest volume?
A) Expiratory reserve volume (ERV)
B) Residual volume (RV)
C) Tidal volume (TV)
D) Functional residual capacity (FRC)
E) Inspiratory reserve volume (IRV)
Inspiratory Reserve Volume (IRV)
The additional amount of air that can be inhaled after a normal inhalation, increasing lung volume beyond the tidal volume.
Expiratory Reserve Volume (ERV)
The additional amount of air that can be forcibly exhaled after a normal exhalation.
Functional Residual Capacity (FRC)
The volume of air remaining in the lungs after a normal, passive exhalation, critical for gas exchange between breaths.
- Recognize and describe the different respiratory volumes and capacities, including tidal volume, expiratory reserve volume, inspiratory reserve volume, and residual volume.

Final Answer :
C
Explanation :
Tidal volume (TV) is the amount of air inhaled or exhaled during normal breathing, which is typically lower in volume compared to the expiratory reserve volume (ERV), residual volume (RV), functional residual capacity (FRC), and inspiratory reserve volume (IRV).
