Front 1

adventitious sounds

Back 1

extra breath sounds that are abnormal, such as crackles, rhonchi, wheezes, and pleural friction rubs

Front 2

chemoreceptor

Back 2

a receptor that responds to a change in the chemical composition (PaCO2 and pH) of the fluid around it

Front 3

compliance

Back 3

a measure of the elasticity of the lungs and thorax

Front 4

crackles

Back 4

short, low-pitched sounds caused by air passing through airway intermittently occluded by mucus, unstable bronchial wall, or fold of mucosa; evident on inspiration and, at times, expiration; similar sound to blowing through a straw under water

Front 5

dyspnea

Back 5

shortness of breath; difficulty breathing

Front 6

elastic recoil

Back 6

the tendency for the lungs to recoil after being stretched or expanded

Front 7

fremitus

Back 7

vibration of the chest wall produced by vocalization

Front 8

mechanical receptors

Back 8

receptors located in lungs, upper airways, chest wall, and diaphragm that are stimulated by irritants, muscle stretching, and alveolar wall distortion

Front 9

pleural friction rub

Back 9

creaking or grating sound from roughened, inflamed surfaces of the pleura rubbing together, evident during inspiration, expiration, or both and no change with coughing; usually uncomfortable, especially on deep inspiration

Front 10

rhonchi

Back 10

continuous rumbling, snoring, or rattling sounds from obstruction of large airways with secretions; most prominent on expiration; change often evident after coughing or suctioning

Front 11

surfactant

Back 11

a lipoprotein that lowers the surface tension in the alveoli

Front 12

tidal volume

Back 12

volume of air exchanged with each breath

Front 13

ventilation

Back 13

inspiration (movement of air into lungs) and expiration (movement of air out of the lungs)

Front 14

wheeze

Back 14

continuous high-pitched squeaking sound caused by rapid vibration of bronchial walls
