7
Q

Boyle’s Law

A

Given a gas of constant temperature, if you increase the volume of the chamber in which the gas is contained, the pressure will decrease

9
Q

Negative pressure

A

Air pressure is less than atmospheric pressure; molecules move farther apart so pressure decreases

26
Q

Cilia

A

Hairlike processes that line the respiratory passageway from the nose to the beginning of the bronchi and beat the pollutants upward and posteriorly

27
Q

Mucus

A

Dense fluid product of mucous membrane tissue

28
Q

Aspiration

A

Entry of liquid or solid materials into the lungs

29
Q

Vertical dimension (of thoracic expansion)

A

The superior-inferior dimension of thorax movement generated by contraction of the diaphragm

30
Q

Transverse dimension (of thoracic expansion)

A

Antero-posterior and lateral dimensional expansion of the thorax generated by contraction of the accessory muscles of inspiration

31
Q

Venules

A

Tiny veins

32
Q

Hiatus

A

Opening

33
Q

Diaphragmatic contraction

A

Expands the lungs, drawing air into them through the bronchial passageway

34
Q

Quiet inspiration

A

Inspiration that involves minimal muscular activity, involves primarily that of the diaphragm

35
Q

Forced inspiration

A

Inspiration that involves both diaphragm and accessory muscles of inspiration

36
Q

Cervical plexus

A

Group of phrenic nerves that anastomoses from the spinal nerves C1-C4

37
Q

Parasternal

A

Near the sternum

38
Q

Forced expiration

A

Reverses the process by pulling the thorax down and in by forcing the diaphragm higher into the thorax

39
Q

Active expiration

A

Expiration arising from muscular activity

40
Q

Passive expiration

A

Expiration arising from passive forces of muscular tissue elasticity

41
Q

Spirometer

A

Decide used to measure respiratory volume

42
Q

Manometer

A

Device used to measure air pressure differences

43
Q

Ventilation

A

Air inhaled per unit time

44
Q

Perfusion

A

Migration of fluid through a barrier

45
Q

Quiet tidal volume

A

Tidal volume at rest, approximately 525cc for male and female adults combined

46
Q

Capacities

A

Combinations of respiratory volumes that express physiological limits

47
Q

Inspiration reserve volume

A

Volume of air that can be inhaled after a tidal inspiration

48
Q

Expiratory reserve volume

A

Volume of air that can be expired after a tidal expiration

49
Q

Residual volume

A

Volume of air remaining after a maximum exhalation

50
Q

Vital capacity

A

Total volume of air that can be inspired after a maximal expiration

51
Q

Functional residual capacity

A

Volume of air remaining in the body after a passive exhalation

52
Q

Total lung capacity

A

Sum of tidal volume, inspiration reserve volume, expiratory reserve volume, and residual volume

53
Q

Inspiratory capacity

A

Maximum inspiratory volume possible after tidal expiration

54
Q

Intraoral (mouth) pressure

A

Pressure that could be measured within the mouth

55
Q

Alveolar (pulmonic) pressure

A

Pressure that is present within the individual alveolus

56
Q

Pleural (intrapleural) pressure

A

Pressure in the space between the parietal and visceral pleurae

57
Q

Pneumothorax

A

Aggregation of air in the pleural space between the lungs and the chest wall, with subsequent loss of the negative intrapleural pressure

58
Q

Atmospheric pressure

A

Pressure on the earth, acts as a constant zero with which to compare respiratory pressures

59
Q

Recoil forces

A

Drive the respiratory system back to equilibrium after inspiration or expiration

60
Q

Checking action

A

Use of muscles of inspiration to impede the outward flow of air during respiration for speech

61
Q

Minute volume

A

Volume of air exchanged by an organism in one minute

62
Q

A

Air within conducting passageways that cannot be involved in gas exchange

63
Q

Respiratory capacity

A
