Flashcards in respiratory system Deck (64):
1

how much do lungs weight?

1 lb each

2

how much air does the lungs hold?

3 quarts

3

how many lobes does the right lung have?

3 lobes (upper, middle, lower)

4

how many lobes does the left lung have? why?

2 lobes bc they make room for the heart

5

trachea? (hows it shaped) (what dose it do)

On the dorsal surface that carries air from larynx to bronchi

6

cilia? (what is it) (what dose it do)

tiny hair like projections that filter and sweep mucus along towards esophagus where they can be swallowed.

7

mucous?

thick stick substance that filters/traps pathogens and dirt in.

8

sinuses location?

in skull surrounding nasal cavity

9

what are sinuses and what do they do?

its warm and moistened air, they give resonance to voice

10

whats the nose made out of?

cartilage.

11

whats the pharynx?

the throat, passageway for both food and air

12

whats the epiglottis

flap of cartilage that covers larynx like a trap door.

13

what does the epiglottis do?

prevents food from entering trachea

14

what's the larynx? what's it made of?

-voice box
-made of primarily cartilage

15

what are 3 sections of pharynx?

nasopharynx, pharyngeal and oropharynx

16

nasopharynx?

upper portion of pharynx behind nasal cavitys

17

pharyngeal?

tonsils

18

oropharynx?

middle section behind oral cavity

19

how's speech produced?

through the larynx, produced when air leaves the lungs the vocal cords vibrate producing sound.

20

whats inspiration and the process?

-process of breathing air in.
-the diaphragm and intercostal muscle contract causing the thoracic cavity to be vacuum like. air rushes through airways to alveoli where exchange of gasses take place.

21

expiration? process?

-diaphragm and intercostal muscles relax
-air is forced out, then an increment of carbon dioxide in blood occurs causing center to increase.

22

external respiration?

exchange of oxygen and carbon dioxide threw lungs and blood stream

23

internal respiration?

exchange of oxygen and carbon dioxide between tissue cells and blood stream

24

cellular respiration?

when cells use oxygen nutrients to produce energy, water and carbon dioxide

25

3 things that happen to air when it enters nasal cavity?

air is warmed, filtered and moistened

26

what color are healthy normal lungs?

pink

27

what are the primary organs?

left lung and right lung

28

what's the diaphragm? what does it do?

-dome shaped fibrous tissue that separates the thoracic cavity from abdomen

29

thoracic volume?

pressure of increasing and decreasing muscles

30

what causes snoring?

narrowing of upper airway during sleep

31

asthma?

condition wear bronchial tubes inflame and result in obstructed
-

32

cause of asthma?

allergy, infection and anxiety

33

symptoms of asthma?

tightness in chest, difficulty breathing, wheezing and coughing

34

treatment of asthma?

anti-inflammatory drugs, oxygen therapy

35

bronchitis?

mucus membrane in the lungs' bronchial passages becomes inflamed.

36

types of bronchitis?

acute and chronic

37

acute bronchitis cause? symptoms?

-caused by viruses or bacteria
-coughing and narrowing of bronchi bc of contraction

38

chronic bronchitis cause? symptoms?

-caused by frequent attacks of acute bronchitis and pollution
-mucus, coughing, wheezing, chest pain and dyspnea

39

COPD cause?

chronic asthma , emphysema, tb, and chronic bronchitis

40

what's emphysema?

it's a non infectious chronic respiratory condition that occurs when walls of alveoli deteriorate and lose elasticity

41

how's emphysema caused and what are symptoms?

-caused by heavy smoking and exposure to air- pollution
- symptoms are dyspnea, suffocation , chronic coughing and cyanosis

42

whats epistaxis? treatment for it?

is a nose bleed that occurs when capillaries in nose become congested and bleed.
-treatment is ice, pressure and leaning forward.

43

whats influenza? symptoms?

a contagious vial infection of upper respiratory system
- fever, chills, muscles, acne, cough and fatigle

44

laryngitis? treatment?

-inflammation of vocal cords
-treatment is rest, fluids, limited voice use

45

lung cancer

leading cause of cancer deaths in men and woman

46

whats pleurisy? symptoms? treatment?

-inflammation of pleura or membranes of lungs occurs in the conjuction with pneumonia
-symptoms are sharp stabbing pains while breathing
-treatment is, rest, meds to relive pain and inflammation

47

pneumonia? cause? symptoms?

-inflammation of the lungs
-caused by bacteria and chemicals
-symptoms are chills, fever, chest pain

48

rhinitis?

its a runny nose, inflammation of nasal mucous membrane

49

what's sinusitis? cause? symptoms?

-inflammation of mucous membrane lining
-caused by bacteria/ viruses
-symptoms are headache, pressure, thick nasal discharge and loss of voice

50

sleep apnea

pauses of breaths when you sleep

51

TB (active)

fever, weight loss, sweats, chest pain, POSITIVE TB TEST

52

TB (dormat)

no symptoms but is postive through the test

53

URI

contagious common cold

54

pleura

membrane or sac in-closed in each lung that allows lungs to expand during breathing

55

two types of pleura and location?

visceral (attached to lungs)
parietal (attached to chest wall)

56

pleural space

space filled with pleural fluid that prevents friction as lungs expand

57

Pleura? Location and function

Lungs, sack of fluid allows lungs to expand during breathing

58

Surfactant location? Function?

- inner surfaces of alveoli
- reduces surface tension of liquid.

59

Alveoli location? Function?

- lungs
- gets rid of carbon dioxide we don't need

60

Esophagus location? Function?

- throat
- pathway for food

61

Hilus location? Function?

- located in the center of the kidney
- blood vessels that enter leave the kidney

62

Bronches location? Function?

- it's in the windpipe in the lungs
