3;2

2
Q

paranasal sinuses are within the following bones except

A

mandible

3
Q

the alveoli are composed of

A

simple squamous epithelium

4
Q

the ____ adheres to the surface of the lungs

A

visceral pleura

5
Q

the ___ is the most inferior cartilage of the larynx

A

cricoid cartilage

6
Q

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

A

nasal conchae

7
Q

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

A

alveolar ducts

8
Q

potential space between visceral and parietal pleurae

A

pleural cavity

9
Q

most inferior portion of the larynx

A

cricoid cartilage

10
Q

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

A

sinus

11
Q

microscopic air sac for gas exchange

A

alveolus

12
Q

consists of large lobes

A

lungs

13
Q

vocal folds, including the opening between them

A

glottis

14
Q

fold of mucous membrane containing elastic fibers responsible for sounds

A

vocal fold

15
Q

increases surface area of nasal mucous membrane

A

nasal conchae

16
Q

passageway for air and food

A

pharynx

17
Q

partially covers opening of larynx during swallowing

A

epiglottis

18
Q

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

A

exchange of gasses through the wall

19
Q

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

A

makes the gas exchange hard because lungs are filled with fluid

true

28
Q

we inhale when the diaphragm contracts

t/f

Q

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

A

residual volume
