lung volumes

Physiology A group of air 'compartments' into which the lung may be functionally divided
Lung volumes  
Expiratory reserve capacity–ERV The maximum volume of air that can be voluntarily exhaled
Functional residual capacity (FRV) Volume left in the lungs at the end of a normal breath which is not normally part of the subdivisions
Inspiratory capacity–IC The maximum volume that can be inhaled
Inspiratory Reserve capacity–IRC The maximum volume that can be inhaled above the tidal volume
Tidal volume–VT The normal to-and-fro respiratory exchange of 500 cc; vital capacity is the maximum amount of exhalable air; after a full inspiration, which added to the residual volume, is the total lung capacity
Total lung capacity–TLC The entire volume of the lung, circa 5 liters
Vital capacity–VC The maximum volume that can be inhaled and exhaled
