2

paranasal sinuses are within the following bones except

mandible

3

the alveoli are composed of

simple squamous epithelium

4

the ____ adheres to the surface of the lungs

visceral pleura

5

the ___ is the most inferior cartilage of the larynx

cricoid cartilage

6

which of the following structures increases the surface area and air turbulence the most during breathing?

nasal conchae

7

which of the following airway tubes would have the smallest lumens?

alveolar ducts

8

potential space between visceral and parietal pleurae

pleural cavity

9

most inferior portion of the larynx

cricoid cartilage

10

air-filled space in skull bone that opens into nasal cavity

sinus

11

microscopic air sac for gas exchange

alveolus

12

consists of large lobes

lungs

13

vocal folds, including the opening between them

glottis

14

fold of mucous membrane containing elastic fibers responsible for sounds

vocal fold

15

increases surface area of nasal mucous membrane

nasal conchae

16

passageway for air and food

pharynx

17

partially covers opening of larynx during swallowing

epiglottis

18

what is the functional advantage of the alveolar walls being so thin?

exchange of gasses through the wall

19

what affect would pulmonary edema have on the function of the alveolar wall?

makes the gas exchange hard because lungs are filled with fluid

20

external oblique

21

a ___ is an instrument to measure air volume during breathing

spirometer

22

the ____ is the maximum volume of air that can be exhaled after taking the deepest breath possible

vital capacity

23

tidal volume is estimated to be about

12-15

25

the contraction of the diaphragm increases the size of the thoracic cavity

t/f

true

26

vital capacity is the total tidal volume, expiratory reserve volume, and residual volume

t/f

false

vital capacities gradually decrease as a person continues to age

t/f

true

28

we inhale when the diaphragm contracts

t/f

true

29

volume of air in addition to tidal volume that leaves the lungs

expiratory reserve volume

30

vital capacity plus residual volume

total lung capacity

31

volume of air that remains in lungs after the most forceful expiration

inspiratory capacity

32

volume of air that enters or leaves lungs during a respiratory cycle

vital capacity

35

maximum volume of air a person can inhale following exhalation of the tidal volume during forced expiration

inspiratory reserve volume

36

volume of air remaining in the lungs following exhalation of the tidal volume

residual volume
