15
Q

What are the names of the lobes in the left and right lung

A

Left - Superior, middle, inferior lobe
right, superior and inferior

16
Q

What are the names of the fissure in the left and right lung?

A

Left - Horizontal fissure (between superior and middle
oblique fissure - between inferior and middle lobe

17
Q

what part of the airway has the most resistance

A

trachea and primary bronchoil, due to smalller crhoss sectional area

18
Q

What is inclued in the Conductionn zone

A

Trachea, primary bronchi and smaller bronchi, and bronchioles

19
Q

What is included in the respiratory zone

A

alveoli

20
Q

difference between bronchi and bronchioles

A

bronchioles lach cartilage discs

21
Q

How many primary bronchi are there

A

2

22
Q

what is the function of a type 1 and type 2 cell in the aveloi and where are they found

A

type 1: gas exchange, large cell on making up most of aveloi
type 2 : synthesize surfactant ( smaller cells on outside of type 1.

23
Q

what does the sufficant do

A

coat the inside of the aveloi and create tension
