17
Q

air must be ________ before it reaches lower respiratory tract

A

conditioned

18
Q

3 parts of air conditioning

A

filtering

humidifying (moistening)

warming

19
Q

how is air filtered?

A

Large particulate matter filtered by hair follicles in nose

Fine matter filtered by mucus

20
Q

how is air humidified?

A

Mucus in respiratory tract humidifies air which flows over it

21
Q

how is air warmed?

A

Capillary beds just beneath nasal cavity surface warm incoming air

22
Q

3 major structures of upper respiratory tract

A

nose

nasal cavity

pharynx

23
Q

function of nose

A

point of entrance into the respiratory system

24
Q

nose is lined with…

A

stratified squamous ep.

25
Q

hair follicles are in the…

A

nose

26
Q

PCCE meaning

A

pseudostratified ciliated columnar epithelia

27
Q

nasal cavity is lined with…

A

PCCE & mucus cells

28
Q

3 functions of mucus

A

traps fine particulate matter in air

traps airborne pathogens

humidifies incoming air

29
Q

function of cilia in nasal cavity

A

move mucus to back of nasopharynx so we can spit or swallow it

30
Q

nasal conchae prevent _______ flow of air

A

laminar

31
Q

what is the problem with laminar flow?

A

it flows in layers that don’t mix, so not all the incoming air will be conditioned by mucus/hair follicles/capillaries

32
Q

function of nasal conchae

A

create an irregular surface over which air flow through the nasal cavity becomes turbulent, allowing all of it to be conditioned

33
Q

function of capillary beds in nasal cavity

A

warm incoming air (blood is warm)

34
Q

function of sinuses

A

contribute mucus to the nasal cavity or pharynx

35
Q

sinuses become inflamed because…

A

they are an ideal habitat for bacteria

36
Q

pharynx is a ____ ________ for respiratory and digestive systems

A

dual passageway

37
Q

3 subregions of pharynx

A

nasopharynx

oropharynx

laryngopharynx

38
Q

the nasopharynx is lined with…

A

PCCE & mucus cells

39
Q

the oropharynx and laryngopharynx are lined with…

A

stratified squamous ep.

40
Q

why do the oropharynx and laryngopharynx need to be lined with stratified squamous ep?

A

it is highly mitotic, which allows it to regenerate quickly when there is damage (high potential for damage in that area from food)

A
