Flashcards in Respiratory System Deck (71):
1

adenoids

Lymphatic tissue in the nasopharynx; pharyngeal tonsils

2

alveolus

Air sac in the lung

3

apex

anatomical tip or uppermost portion of the lung.

4

Base

anatomical Lower portion of the lung

5

Bronchioles

Smallest branches of the bronchi. Terminal bronchioles lead to alveolar ducts

6

bronchus

Branch of the trachea that is a passageway into the lung; bronchial tube

7

Co2

Gas produced by body cells when oxygen and carbon atoms from food combine; exhaled through the lungs.

8

cilia

Thin hairs attached to the mucous membrane epithelium lining the respiratory tract. They function to clear bacteria and foreign substances from the lung. Smoking impairs the cilia function

9

diaphragm

muscle separating the chest and abdomen. It contracts to pull air into the lungs and relaxes to push air out

10

epiglottis

Lid-like piece of cartilage that covers the larynx, preventing food from entering the larynx and trachea during swallowing

11

expiration

breathing out

12

glottis

slit-like opening into the larynx

13

hilum of the lung

Midline region where the bronchi, blood vessels, and nerves enter and exit the lungs. Hilar means pertaining to the hilum

14

inspiration

breathing in

15

larynx

voice box; containing the vocal cords.

16

lobe

division of a lung

17

mediastinum

region between the lungs in the chest cavity. contains the trachea, heart, lymph nodes, aorta, esophagus, and bronchial tubes

18

nares

openings through the nose carrying air into the nasal cavities

19

O2

gas that makes up 21% of the air. It passes into the bloodstream at the lungs and travels to all body cells.

20

palatine tonsil.

One pair of almond-shaped masses of lymphatic tissue in the oropharynx

21

paranasal sinus

One of the air cavities in the bones near the nose.

22

parietal pleura

Outer layer of pleura lying closer to the ribs and chest wall.

23

pharynx

throat; including the nasopharynx, oropharynx, and laryngopharynx

24

pleura

double layered membrane surrounding each lung.

25

pleural cavity

Space between the folds of the pleura

26

pulmonary parenchyma

Essential parts of the lung, responsible for respiration; bronchioles and alveoli.

27

respiration

breathing

28

trachea

windpipe

29

visceral pleura

inner layer of pleura lying closer to the lung tissue.

Tapping on a surface to determine the difference in the density of underlying structures

66

pleural rub

Scratchy sound produced by the pleural surfaces rubbing against each other

67

rales (crackles)

Fine crackling sounds heard on auscultation (during inhalation) when there is fluid in the alveoli

68
