Functions of Respiratory System

1. Provides gas exchange between air and circulatory system
2. Move air to and from exchange surface of lung
3. Protects respiratory surfaces from dehydration, temperature change, and infection
4. Produce sounds for speaking and communication
5. Provide olfactory sensation to CNS from nasal cavity
6. Controls pH

2

Division of Respiratory

Upper Respiratory and Lower Respiratory

3

filters and humidifies incoming air

upper respiratory

4

contains delicate conductions surfaces and alveolar exchange surfaces

lower respiratory

5

the underlying layer of areolar

lamina propria

6

What type of epithelial tissue is in the nasal cavity

Pseudostratified ciliated columnar

7

What type of epithelial tissue is in the pharynx

Stratified squamous

8

What type of epithelial tissue is in the lower respiratory

Pseudostratified ciliated columnar

9

What type of epithelial tissue is in the alveoli

Simple squamous

10

the cilia of pseudostratified columnar cells sweep the passage and move mucus which has trapped debris

ciliary escalator system

11

cells that produce mucous

goblet cells ( simple columnar cells)

12

A disease that makes thick mucous that blocks air passage making O2 passage impossible

cystic fibrosis

13

external opening of nasal cavity

external nares (nostrils)

14

lies within nose is posterior region divided by septum

nasal cavity

15

part of the nasal cavity that is superior to nostrils, lined with skin, contains sebaceous glands and sweat glands, as well as vibrissae

vestibule

16

forms roof of mouth

hard and soft palate

17

nostril openings into throat

internal nares

18

mucous producing tissue, consisting of lamina propria and epithelial tissue

nasal mucosa

19

shared by the respiratory and digestive system

pharynx

20

3 sections of pharynx

nasopharynx
oropharynx
laryngopharnx

21

superior portion of nasal cavity, air passage way, epithelium produces mucous, houses pharyngeal tonsil

nasopharynx

22

middle portion of nasal cavity, air and food passage way, epithelium changes to deal w/ abrasive food, houses palatine and lingual tonsils

oropharynx

23

area between hyoid bone and esophagus, increases mucosal surface area exposed to air and enhance air turbulence in nasal cavity

laryngopharynx

24

voice box, protects glottis, attaches to hyoid bone

larynx

25

Functions of Layrnx

provides open air pathway
acts as switching mechanism to properly route air
produces vocal sounds

26

large unpaired cartliage

thyroid
cricoid
epiglottis

27

small paired cartliage

arytenoid
corniculate
cuneform

28

larynx folds

inelastic vestibular fold
vocal folds

29

When swallowing the glottis is closed by the _______ and covered by the epiglottis

vestibular folds

30

Air passing through the glottis vibrates the ________ producing sound waves

vocal folds
