only external and visible part of the respiratory system

A

nose

2
Q

muscles of respiratory system

A

diaphragm, internal/external intercostals

3
Q

septum

A

perpendicular plate in the vomer

4
Q

has voice box and epiglottis

A

larynx

5
Q

epiglottis is made of

A

elastic cartilage

6
Q

keeps air passages open

A

thyroid cartilage (type of hyaline cartilage)

7
Q

cilated mucosa lining the trachea is what type of tissue

A

pseudostratified cilated columnar epithelium

8
Q

cilia

A

finger like projections important for moving the mucus out of the airway and into the esophagus

9
Q

bronchi enter the lung at the

A

hilum

10
Q

lungs wrapped in

A

visceral pleura

11
Q

body cavity lined with

A

parietal pleura

12
Q

lobes in left and right lung

A

2 and 3

13
Q

pleural fluid

A

fluid in between visceral and parietal pleura that prevents sticking

14
Q

top of lung near clavicle

A

apex

15
Q

positive air pressure

A

in lungs means the lungs always have air in them so they don’t completely collapse

16
Q

alveolar pores

A

connect the different alveoli

17
Q

where gas exchange takes place

A

pulminary capillaries in the alveoli

18
Q

type of tissue found in alveoli

A

simple squamous epithelium

19
Q

air-blood barrier

A

formed by alveolar walls where blood in the capillaries meets the air so that gas exchange can take place

20
Q

moisturizes alveolar membranes

A

surfactant

21
Q

alveolar macrophages

A

protect gas exchange process from invasion from bacteria, foreign particles

22
Q

tidal volume moves about

A

500 ml of breath

23
Q

Inspiratory reserve volume

A

how much more you can forcibly breath in past tidal volume. about 3100 ml

24
Q

expiratory reserve volume

A

how much you can forcibly exhale after tidal volume. about 1200 ml

25
Q

residual volume

A

air remaining in lung after expiration. about 1200 ml

26
Q

vital capacity

A

tidal volume+ inspiratory reserve volume+ expiratory reserve volume. Men:4800 women: 3100

27
Q

dead space volume

A

air that never reaches the lungs. about 150 ml

28
Q

functional volume

A

air that actually reaches the respiratory zone. about 350 ml

29
Q

volition

A

conscious control of breathing

30
Q

most important factor for breathing rate

A

CO2 levels

31
Q

results when blood becomes alkaline

A

hypoventalation
