Flashcards in 16 - The Respiratory System Deck (57):
0

Small sacs in the lungs that fill with air from the alveolar ducts (singular alveolus).

Alveoli

1

The larger air passages in the lungs.

Bronchi

2

A tiny branch of the bronchi that connects to the alveoli.

Bronchiole

3

The outer curved part of the nasal cavities that acts as a filter for dust, and to warm and moisten the incoming air.

Choana

4

A dome-shaped muscle between the thoracic and abdominal cavities; controls regular, relaxed breathing by contracting and relaxing.

Diaphragm

5

A cartilaginous flap above the glottis that closes while food or liquid is passing through the pharynx.

Epiglottis

6

Breathing out

Exhalation

7

Another term for exhalation (breathing out).

Expiration

8

The vocal cords and the opening between them.

Glottis

9

Breathing in

Inhalation

10

Another term for inhalation (breathing in).

Inspiration

11

The bottom part of the pharynx.

Laryngopharynx

12

The voice box

Larynx

13

The main breathing organs in the chest that bring oxygen into the body and expel carbon dioxide.

Lungs

14

Any of the passages in the nasal passages.

Nasal cavity

15

The part of the pharynx behind the nasal cavity and above the soft palate.

Nasopharynx

16

External openings of the nose that provide air passage and secretions from the nose and eyes.

Nostrils

17

The part of the throat located at the back of the mouth.

Oropharynx

18

The outer layer of the pleural membrane.

Parietal pleura

19

The cavity at the back of the mouth that opens to the esophagus and larynx.

Pharynx

20

The volume of air left in the lungs after a maximum exhalation.

Residual volume

21

An air-filled cavity

Sinus

22

The volume of air that is inhaled or exhaled during a normal, resting breathing cycle.

Tidal volume

23

The volume of air in the lungs after a maximum inhalation.

Total lung capacity

24

The inner layer of the pleural membrane

Visceral pleura

25

The volume of gas that can be exhaled from the lungs at maximum inhalation.

Vital capacity

26

A number of conditions in which the lungs receive inadequate oxygen; may be caused by a pathological condition or by exposure to smoke, pollution, or toxic chemicals, resulting in shortness of breath.

Acute respiratory disease syndrome (ARDS)

27

The temporary cessation of breathing (usually occurs during sleep)

Apnea

28

A condition caused by an inadequate intake of oxygen.

Asphyxia

29

The accidental inhalation of foreign matter into the bronchial system.

Aspiration

30

A disease characterized by narrowing of the bronchial tubes, making breathing difficult.

Asthma

31

Abnormally slow breathing

Bradypnea

32

Inflammation of the bronchi

Bronchitis

33

An irregular breathing pattern consisting of periods of maximum respiration followed by a progressive decrease until apnea results; often seen in comatose or brain-injured patients.

Cheyne-Stokes respiration

34

A progressive disease characterized by shortness of breath, wheezing, and chronic coughing, usually caused by smoking; usually a combination of chronic bronchitis and emphysema.

Chronic obstructive pulmonary disease (COPD)

35

Profuse discharge from the mucous membrane of the nose.

Coryza

36

A common genetic disorder of infants and children in which thick, viscous mucus is produced in the respiratory tract; the exocrine glands do not secrete properly, and a predisposition to bacterial infections exists in the lungs.

Cystic fibrosis

37

Shortness of breath

Dyspnea

38

A lung disease in which tissue deterioration results in increased air retention and reduced exchange of gases. The result is difficulty breathing and shortness of breath; usually caused by smoking.

Emphysema

39

A common nosebleed

Epistaxis

40

A seasonal rhinitis resulting from an allergic reaction to pollen.

Hay fever

41

Coughing up blood from lungs or airways

Hemoptysis

42

An involuntary spastic contraction of the diaphragm.

Hiccup

43

Abnormally deep or fast respiration, in which excessive quantities of air are taken in, causing buzzing in the ears, tingling in the extremities, and sometimes fainting.

Hyperventilation

44

An acute viral infection involving the respiration tract and other body systems.

Influenza

45

A cancerous growth in the lung tissue.

Lung cancer

46

An inflammation of the covering around the lungs.

Pleurisy

47

An inflammation of the lungs caused by a bacterial or viral infection, which causes fever, shortness of breath, and the coughing up of phlegm (mucus and other material produced by the lining of the respiratory tract; also called sputum).

Pneumonia

48

A collapsed lung caused by accumulation of air or gas in the space between the lung and chest wall.

Pneumothorax

49

The abnormal collection of fluid in the lungs.

Pulmonary edema

50

An inability of the lungs to conduct gas exchange.

Respiratory failure

51

Asthma, hay fever, and other conditions caused by oversensitivity of any part of the respiratory system.

Respiratory hypersensitivity

52

A failure to provide adequate oxygen to the cells of the body and remove carbon dioxide.

Respiratory insufficiency

53

An inflammation of mucous membranes in the nose; the common cold.

Rhinitis

54

Pain or discomfort from inflammation of any combination of the tonsils, larynx, or pharynx; also called pharyngitis.

Sore throat

55

Exaggeratedly rapid breathing

Tachypnea

56

A contagious, life-threatening disease caused by a bacterial infection and spread through person-to-person contact.

Tuberculosis
