|
Lack or cessation of breathing
|
apnea
|
|
|
Normal breathing in terms of rate and depth
|
eupnea
|
|
|
labored breathing or "air hunger"
|
dyspnea
|
|
|
Chronic oxygen deficiency
|
hypoxia
|
|
|
condition characterized by fibrosis of the lungs and an increase in size of the alveolar chambers.
|
emphysema
|
|
|
condition characterized by increased mucus production, which clogs repiratory passageways and promotes coughing.
|
chronic bronchitis
|
|
|
repiratory passageways narrowed by bronchiolar spasms
|
asthma
|
|
|
Together called COPD
|
emphysema and chronic bronchitis
|
|
|
incidence strongly associated with cigarette smoking; outlook is poor.
|
lung cancer
|

|
infection spread by airborne bacteria; a recent alarming increase in drug users and AIDs victims.

|
|
respiratory volume inhaled or exhaled during normal breathing.
|
Tidal volume.
|
|
|
air in respiratory passages that does not contribute to gas exchange
|
dead space volume
|
|
|
total amount of exchangable air
|
residual volume
|
|
|
gas volume that allows gas exchange to go on continuously
|
expiratory reserve volume
|
|
|
Amount of air that can still be exhaled (forcibly) after normal exhalation.
|
vital capacity
|
|
|
all gas exchanges are made by
|
diffusion
|
|
|
Multiplying the tidal volume at rest by the number of breaths per minute yields a number called the
|
total minute volume
|
|
|
about 99% of the total atmospheric pressure at sea level is exerted by which two gasses?
|
N2 and O2
