1

Two pairs of vocal folds are found in the larynx. Which pair are the true vocal cords (superior or inferior)?

Inferior vocal folds

2

Forms the Adam's apple

Thyroid cartilage

3

Shaped like a signet ring

Cricoid cartilage

4

a "lid" for the larynx

Epiglottis

5

vocal cord attachment

arytenoid cartilages

6

What is the significance of the fact that the human trachea is reinforced with cartilaginous rings?

Reinforce the trachea walls to maintain its open passageway regardless of the pressure changes that occur during breathing.

7

Of the fact that the rings are incomplete posteriorly?

Allows esophagus to expand anteriorly when a large food bolus is swallowed.

8

What is the function of the pleural membranes?

Produce lubricating serous fluid that causes them to adhere closely to one another, holding the lungs to the thoracic wall and allowing them to move easily against one another.

9

Name two functions of the nasal cavity mucosa.

It warms, moistens and filters the air that passes through the nasal cavity.

10

Which s longer?

Left main bronchus

11

Larger in diameter?

Right main bronchus

12

More horizontal?

Left main bronchus.

13

Which more commonly traps a foreign object that has entered the respiratory passageways

Right main bronchus

14

connects the larynx to the primary bronchi

trachea

15

site of tonsils

pharynx

16

food passageway posterior to the trachea

esophagus

17

covers the glottis during swallowing of food

epiglottis

18

contains the vocal cords

larynx

19

nerve that activates the diaphragm

phrenic nerve

20

pleural layer lining the walls of the thorax

parietal pleura

21

site from which oxygen enters the pulmonary blood

alveolus

22

connects the middle ear to the nasopharynx

pharyngotympanix tube

23

openining between the vocal folds

glottis

24

increases air turbulence in the nasal cavity

conchae

25

separates the oral cavity from the nasal cavity

palate

26

external respiration

The gas exchange between the blood and the air filled chambers of the lungs (oxygen loading/carbon dioxide unloading).

27

internal respiration

Exchange of gases between systemic blood and tissue cells (oxygen unloading and carbon dioxide loading).

28

cellular respiration

Body cells require an abundant and continuous supply of oxygen. As the cells use oxygen, the release carbon dioxide , a waste product that the body must get rid of.
