Term
Types of Lung Volumes
Definition
Tidal volume, inspiratory reserve volume, expiratory reserve volume, residual volume, dead air
Term
Types of Lung Capacities
Definition
Vital capacity, functional residual capacity, inspiratory capacity, total lung capacity
Term
Lung Volume
Definition
Partitioning off of respiratory system to get an accurate estimate of amount of air each compartment can hold; discrete amounts
Term
Lung Capacity
Definition
More functional units; refer to combinations of volumes that express physiological limits; represent functional combinations of volumes
Term
Tidal Volume
Definition
The volume of air exchange in one cycle of respiration
Term
Inspiratory Reserve Volume
Definition
The volume of air that can be inhaled after a tidal inspiration
Term
Expiratory Reserve Volume
Definition
The volume of air that can be expired following passive, tidal expiration; also know as resting lung volume
Term
Residual Volume
Definition
The volume of air remaining in the lungs after a maximum exhalation
Term
Vital Capacity
Definition
The volume of air that can be inhaled following a maximal exhalation; includes inspiratory reserve volume, tidal volume, and expiratory reserve volume
Term
Functional Residual Capacity
Definition
The volume of air in the body at the end of passive exhalation; includes expiratory reserve and residual volumes
Term
Inspiratory Capacity
Definition
The maximum inspiratory volume possible after tidal expiration
Term
Total Lung Capacity
Definition
The sum of inspiratory reserve volume, tidal volume, expiratory reserve volume, and residual volume
