2

What epithelium lines the nasal cavity?

Pseudostratified ciliated with goblet cells

3

LABEL 

 

Superior, middle, inferior concha

4

What is the function of the nasal cavity?

Filters and humidifies air Smells

5

6

Whats the name of the tube which connects the nasopharynx to the middle ear cavity?

eustachian tube

7

Where are the vocal cords located?

in the larynx

8

What is the function of the vocal cords?

Prevents food entering the trachea

9

What controls the movement of the vocal cords and what is the name of the nerve that supplies them? How does the pathway of the nerve differ on the left and right side of the body?

Muscles of larynx.

Nerve - Recurrent laryngeal muscles

Left - curves underneath arch of aorta

Right - curves underneath subclavian artery

10

How many main bronchi are on the right and on the left?

3 on the right, 2 on the left

11

Name the divisions of the bronchus

Bronchus --> Lobar Bronchi --> Segmental bronchi --> subsegmental bronchi --> bronchioles --> terminal bronchioles --> alveolar ducts --> alveoli

12

What is the epithelium of the pharynx?

psuedostratified ciliated with goblet cells

13

What is the epithelium of the Larynx?

psuedostratified ciliated with goblet cells

14

What is the epithelium of the Trachea?

psuedostratified ciliated with goblet cells

15

What is the epithelium of the lobar bronchi?

psuedostratified ciliated with goblet cells

16

What is the epithelium of the bronchioles?

Simple cuboidal ciliated with clara cells

17

What is the epithelium of the alveolar ducts?

Simple cuboidal with clara cells

18

What is the epithelium of the terminal bronchioles?

Simple cuboidal with clara cells

19

What is the epithelium of the alveoli?

simple squamous

20

What happens to pulmonary blood flow when pO2 is low?

local vasoconstriction

21

22

What complications can occur in a viral URTI?

• Can spread to the sinuses via their openings in the nasal cavity

• Can spread to middle ear via eustachian tube

 

 

23

How can a decrease of pharyngeal muscle tone result in sleep apnoea?

sleep apnoea (decrease of pharyngeal muscle tone during sleep results in muscles becoming floppy and tongue obstructing trachea during sleep)

24

What is the name of the 2 layers of the pleural sac?

visceral and parietal

25

What is the name of the space between the 2 layers of the pleural sac?

pleural cavity

26

27

Define pressure

Gas molecules hitting the sides of a container

28

What is boyle's law?

Pressure inversely proportional to volume

29

What is charles' law?

Higher temp = higher pressure

30

How do you calculate partial pressure?

the same fraction of the total pressure as the volume fraction of the gas in the mixture.

31

Is partial pressure dependent on the size of the molecule or the number of molecules or both?

dependent on number of molecules

32

What is saturated vapour pressure?

when equilibrium is reached in terms of water molecules entering and leaving the water

33

What is saturated vapour pressure dependent on?

Temperature

34

What is gas tension? What does it indicate?

Gas tension is the rate at which molecules of gas in the water hit the walls of the liquid and the interface between liquid and gas, and therefore indicates how readily the gas leaves the liquid.

35

Define content of a liquid

• Content = solubility x tension •

Some liquids bind much more gas than others. Content is therefore the amount of gas in a liquid.

36

Define the tidal volume

The lung volume that represents the amount of air that is displaced between normal inspiration and expiration when extra effort is not applied.
