Respiratory System Lec & Lab

Question 1

e volume of air inspired or expired
with each breath. At rest, quiet breathing results in a tidal
volume of about 500 milliliters (mL)

Answer 1

TidalVolume

Question 2

the volume of air still remaining in the
respiratory passages and lungs after maximum expiration
(about 1200 mL).

Answer 2

Residual Volume

Question 3

amount of air that can
be inspired forcefully beyond the resting tidal volume
(about 3000 mL).

Answer 3

IRV

Question 4

the amount of air that can
be expired forcefully beyond the resting tidal volume
(about 1100 mL).

Answer 4

ERV

Question 5

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).

Answer 5

Functional Residual Capacity

Question 6

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).

Answer 6

Inspiratory Capacity

Question 7

s the sum of the inspiratory reserve volume,

the tidal volume, and the expiratory reserve volume.

Answer 7

Vital Capacity

-maximum inspiration and expiration

s the sum of the inspiratory and
expiratory reserves and the tidal and residual volumes
(about 5800 mL
