Total lung capacity
Achieved by maximal inspiration
The largest amount of air that can possibly be held in the lungs
Maximal inspiration
The maximum amount of air you can inhale
Maximal expiration
Maximum amount of air you can exhale - not all air can be expelled from the lungs
Tidal volume
VT
The volume of a single breath
Functional residual capacity
Amount of air in the lungs at the end of a normal relaxed expiration
Residual volume
VR
Minimal volume of air that can be left in the lung
