Definitions:

Functional Residual Capacity (FRC)

The volume of air remaining in the lungs after a normal, passive exhalation, critical for gas exchange between breaths.

Tidal Volume (TV)

The volume of air moved into or out of the lungs during a normal breath, at rest.

Residual Volume (RV)

The volume of air remaining in the lungs after a maximal exhalation, preventing lung collapse and ensuring continuous gas exchange.

Inspiratory Reserve Volume (IRV)

The extra volume of air that can be breathed in beyond a standard breath.
