Eupnea
33
Alveolar ventilation -
the air that reaches the alveoli for respiration
34
Apnea -
stopped breathing
35
Tachypnea -
rapid shallow breathing
36
Hyperpnea -
increased rate of deep breathing
37
Bradypnea -
slow breathing
38

difficult breathing
39
Sinusitis -
inflamed sinus
40
- artificial surgical opening of the trachea
Tracheostomy
41
- closing of the glottis to prevent exhalation during straining
Valsala’s maneuver
42
- procedure to dislodge an object in the airway
heimlich maneuver
43
- inflammation of the lungs?
pleurisy
44
- permit enlargement of the alveoli and destruction of the alveolar wall; results in a loss of elasticity
emphysema
45
- double layered serosa of lungs
pleura
46
- lines the thoracic wall
parietal pleura
47
- covers lungs
visceral pleura
48
- fluid reduces friction
intrapleural serous
49
- inflammation of the pleura; results in painful breathing
pleurisy
50
- a lipoprotein that is secreted by the alveolar cells to reduce surface tension; keeps alveoli from collapsing
