WebFRC is functional residual capacity. FRC is the volume remaining in the lungs after normal and passive exhalation. FRC keeps the small airways open and it prevents the complete emptying of the lungs during each respiration cycle. FRC increases due to increase in both respiration frequency and tidal volume. 5.
