Lung Volumes

Question 1

tidal volume

Answer 1

volume of air entering or leaving the lungs during a single breath

Question 2

inspiratory reserve volume

Answer 2

extra volume of air that can be maximally inspired over and above the typical resting tidal volume

Question 3

inspiratory capacity

Answer 3

maximum volume of air that can be inspired at the end of a normal quiet expiration

Question 4

expiratory reserve volume

Answer 4

extra volume of air that can be actively expired by maximal contraction beyond the normal volume of air after a resting tidal volume

Question 5

residual volume

Answer 5

minimum volume of air remaining in the lungs, even after a maximal expiration

Question 6

functional residual capacity

Answer 6

volume of air in lungs at the end of normal passive expiration

Question 7

vital capacity

Answer 7

maximum volume of air that can be moved out during a single breath, following a maximal inspiration

Question 8

total lung capacity

Answer 8

maximum volume of air that lungs can hold

Question 9

forced expiratory volume in one second (FEV1/dynamic volume)

Answer 9

volume of air that can be expired during the first second of expiratory
