1

Oxygen and CO2 exchange
Olfaction
Phonation
Defense
and Conditioning of air are all functions of what?

Respiratory system

2

What is the respiratory portion of the respiratory system

O2 and CO2 exchange

3

What is the conducting portion of the respiratory system

Olfaction
Phonation
Defense
And conditioning of air

4

True or false; along with warming and moistening the air, conditioning of the air refers to filtration of large to small particulate

true

5

True or false; the conduction portion of the respiratory system transport air to the respiratory portion

true

6

The surface epithelium of the nasal vestibule is made up of what?

keratinized stratified squamous epithelium

7

What kind of glands would you find in the vestibule of the nasal cavity

sweat and sebaceous

8

What kind of cartilage makes up the vestibule of the nasal cavity

hyaline

9

True or false; the mucociliary apparatus in the respiratory region of the nose filters medium size particulate

true

10

Where would you find seromucus glands in the nose?

lamina propria

11

The mucus portion of the serumucus glands of the nose functions to

humidify air
mucocililary clearance

12

The serous products produced by the seromucus glands of the nose act as a...

small particulate filter : Lysozyme (antibacterial) Interferons (antiviral) Cytokines (stimulate defense cells)

13

True or false; along with the seromucus glands, in the lamina propria of the nose you would expect to find a cavernous plexus with many large venules typically filled with blood

true

14

What are the 3 functions of the cavernous plexus in the lamina propria of the nose

Warm air
Humidify air
Provide defense (inflammation within lamina propria - stuffy nose - also increased blood -> increased O2 -> stimulate seromucus secretion -> runny nose)

15

True or false; the Paranasal sinuses are found in the ethmoid, sphenoid, frontal and maxilla bones; and connect to nasal cavity

true - connects through sinal ostia

16

Do the paranasal sinuses have a lamina propria?

yes; but is thin - has seromucus glands and quite vascular

17

What possible problem can arise due to small ostia connecting paranasal sinuses

inflammation can cause a blockage and subsequent sinus infection

18

What are the 3 subdivisions of the pharynx

Nasopharynx (superior)
Oropharynx (middle)
Laryngopharynx (inferior)

19

What kind of cells cover the surface epithelium of the mucosa of the nasopharynx

Respiratory epithelium - Mucociliary clearance

20

What kind of cells cover the surface epithelium of the mucosa of the oropharynx and Laryngopharynx

stratified squamous epithelium

21

True or false; the whole respiratory system has no muscularis mucosa

true

22

What would you expect to find in the lamina propria (loose ct.) of the nasopharynx

Pharyngeal and tubal tonsils

23

What would you expect to find in the lamina propria (loose ct.) of the Oropharynx

Lingual and palatine tonsils

24

Would you expect to see any tonsils in the lamina propria (loose ct.) of the Laryngopharynx

no

25

True or false; the submucosa of the pharynx = Pharyngobasilar fascia

true; Collagen in periosteum of basilar portion of occiput blends into wall of pharynx

26

What function does the submucosa of the pharynx (Pharyngobasilar fascia) have?

Adds support to 90 degree turn of head

27

What kind of muscle makes up the muscularis externa of pharynx? What is unique about the fiber arrangement?

All skeletal muscle

Unique because reverse pattern - Longitudinal inner and Circular outer (this arrangement also occurs in uterus)

28

True or false; the Adventitia of the pharynx = Buccopharyngeal Fascia

true

29

True or false; the Epimysium of buccinator muscle blends into the adventitia of pharynx (Buccopharyngeal fascia)

true

30

What kind of cells line the surface epithelium of the mucosa of the trachea

Respiratory epithelium
