respiratory phys Test

Enter the letter for the matching Answer
incorrect
1.
surfactant
incorrect
2.
vital capacity
incorrect
3.
muscels of inspiration
incorrect
4.
Inspiratory capacity
incorrect
5.
residual volume
incorrect
6.
functional residual capacity
incorrect
7.
alveolar ventillation
incorrect
8.
tidal volume
incorrect
9.
inspiratory reserve volume
incorrect
10.
compliance of respiratory system
A.
volume that can be inspired over and above tidal volume
B.
volume that remains in the lungs after maximal expiration
C.
volume inspired or expired with each normal breath
D.
sum of tidal volume and inspiratory reserve volume
E.
( tidal volume- dead space) X respiration rate
F.
distensibility of lungs and chest wall; inversly related to elastance
G.
reduces surface tension and increases compliance, is produced starting gestational week 24-35
H.
volume of air that can be forcibly expired after maximal inspiration
I.
sum of expiratory reserve volume and residual volume; remains in lungs after tidal volume is expired
J.
diaphragm and external intercostals
Type the Question that corresponds to the displayed Answer.
incorrect
11.
synthesized by type II alveolar cells and consits primarily of DPPC; lecithin:sphingomyelin ratio >2:! indicates mature levels of surfactant
incorrect
12.
tidal volume + inspiratory reserve volume+ expiratory reserve volume
incorrect
13.
alveolar pressure becomes postitive, intrapleural pressure returns to resting value
incorrect
14.
volume that can be expired after the expiration of a tidal volume
incorrect
15.
functional measurement, volume of the lungs that does not participate in gas exchange
incorrect
16.
volume in conductin airways
incorrect
17.
tidal volume X respiration rate
incorrect
18.
normally passive, used during exercise; includes abdominal muscles and internal intercostals
incorrect
19.
alveolar pressure becomes negative causing a presure gradient, intrapleural pressure becomes more negative
incorrect
20.
alveolar pressure equals atmospheric pressure, intrapleural pressure is negative
