Respiratory System Lec & Lab Flashcards
e volume of air inspired or expired
with each breath. At rest, quiet breathing results in a tidal
volume of about 500 milliliters (mL)
TidalVolume
the volume of air still remaining in the
respiratory passages and lungs after maximum expiration
(about 1200 mL).
Residual Volume
amount of air that can
be inspired forcefully beyond the resting tidal volume
(about 3000 mL).
IRV
the amount of air that can
be expired forcefully beyond the resting tidal volume
(about 1100 mL).
ERV
e expiratory reserve
volume plus the residual volume. This is the amount of air
remaining in the lungs at the end of a normal expiration
(about 2300 mL at rest).
Functional Residual Capacity
tidal volume plus the inspiratory
reserve volume. This is the amount of air a person can
inspire maximally after a normal expiration (about
3500 mL at rest).
Inspiratory Capacity
s the sum of the inspiratory reserve volume,
the tidal volume, and the expiratory reserve volume.
Vital Capacity
-maximum inspiration and expiration
s the sum of the inspiratory and
expiratory reserves and the tidal and residual volumes
(about 5800 mL
