3 lung capacities
inspiratory capacity, vital capacity, functional residual capacity
the greatest amount of air that can be inspired from a resting expiratory level
inspiratory capacity
the greatest amount of air that can be exhaled following a maximal inhalation
vital capacity
the amount of air left in the lungs at the end of a normal expiration
functional residual capacity
4 lung volumes
inspiratory reserve volume, tidal volume, expiratory reserve volume, residual volume
the greatest amount of air that can be inspired at the end of normal inspiration
inspiratory reserve volume
the amount of air that is inspired/expired in a normal breath
tidal volume
the greatest amount of air that can be expired at the end of a normal expiration
expiratory reserve volume
the amount of air that is left in the lungs following a maximal exhalation
residual volume
which lung volume is most responsive during exercise?
tidal volume
