Flashcards in CHapter 13 test Deck (64):
1

Respiration

exchange of gasses among lining things and their environment

2

internal respiration

exchange of gasses between blood and body cells

3

diaphram

main muscle involved in breathing

4

external respiration

exchange of gases between air in lungs and blood

5

expiration

to exhale

6

pulmonary ventilation

breathing

7

inspiration

to inhale

8

The exchange of both 02 & C02 from blood to body tissue occurs by

diffussion

9

spirometer

measures the amount of air exchanged in breathing

10

vital capacity

maximum expiration

11

tidal capacity

normal inspiration/expiration

12

expiratory reserve volum

amount of air that can forcibly exhaled after inspiring tidal volume

13

inspiriatory reserve volume

amount of air that can be forcibly inhaled after normal inspiration

14

What do chemo receptors control?

levels of CO2, 02 and acid in the body

15

what do stretch receptors control?

elasticity of the lungs

16

How do the chemo receptors control it?

receptors near the cartaroid artery send signals to the brain when C02 is too high or 02 is too low

17

How do the stretch receptors control it?

when we inspire TV, signals are sent to the inspiratory center to tell our breathing muscles to relax

18

Respiratory arrest

failure to resume breathing after a long period of apnea

19

Apnea

complete stoppage of breathing for a brief period

20

Hypoventilation

labored or difficulty breathing

21

Hyperventilation

rapid & deep respiration

22

Eupnea

normal respiratory rate

23

Dyspnea

slow & shallow respiration

24

What four things does the respiratory system do to the air we breathe?

gas exchange
warms
filters the air
humidifies

25

What is the respiratory mucosa and what does it do?

lines your tubes, produces mucous

26

What is the difference between the Respiratory Mucosa and Respiratory Membrane?

Mucosa onlyu lines your tubes, membrane lines the whole system. And membrane separates capillaries and aveoli

27

How much mucus is produced daily?

125mL

28

What are the three major parts of the Upper Respiratory Tract?

nose
pharynx
larynx

29

Air enters the respiratory tract through the

nostrils

30

what does the nasal septum separate?

the two nasal cavities

31

What are the four paranasal sinuses

frontal
sphenoidal
maxillary sinus
ethmoid

32

What are these four sinuses line with?

mucous

33

What does the lacrimal sac drain into the nasal cavity?

tears

34

WHy is breathing through the nose better for humidifying the air than breathing through the mouth?

The cilia helps trap the dust and bacteria . Conchae is in the nose and helps humidify the air

35

another name for the pharynx

throat

36

In order, superiorly to inferiorly, what are three portions of the pharynx

nasal pharynx
oro pharynx
larngo pharynx

37

if both food and air pass through the pharynx where do they separate to go to their destination?
air:
food:

larynx/trachea
stomach/ esophagus

38

Another name for larynx

voice box

39

Consists of __________ the largest part being called the ______

cartilage
adam's apple

40

Explain how vocal cords can change the pitch of your voice

the muscles that attached to your larynx tighten they have a higher pitch

41

What purpose does the epiglottis serve

so food doesn't go down your windpipe

42

What are the three major parts of the lower repiratory tract

trachea
all of the bronchial tree
lungs

43

another name for the trachea is

windpipe

44

what is trachea made up of?

cartilage

45

What does this prevent the trachea from doing?

collapsing

46

what is the trachea lined with

mucous

47

The Primary Bronchi (right & left bronchus) leads into the

right and left lung

48

The Secondary Bronchi are found in the _______ & branch out getting _______

lungs
smaller

49

like the trachea & primary bronchi these tubes are lined with

mucous

50

Bronchioles are smaller tubes of the bronchi are made up of

smooth

51

At the end of the bronchioles we find

alveolar duct -----> alveolar sac -------> alvolar

52

What is the surface of each alveoli lined with?

surfactant

53

What purpose does surfactant serve?

reduces tension of alveoli

54

How many loves does the right lung have?

3

55

How many lobes does the left lung have?

2

56

WHat do the Pleura cover?

the surface of the lungs

57

what does the pleura they line?

inner surface of the rib cage?

58

What is the purpose of the pleura?

to keep the membranes from rubbing together

59

Influenza

known as the flue

60

pneumonia

fluid builds up in your lungs

61

tuberculosis

disease affecting the lungs

62

asthma

air passages become narrow

63

bronchitis

inflammation and swelling of bronchioles

64
