Chap: 3 Anatomy Of Respiration

Question 1

Passive expiration

Answer 1

Expiration arising from passive forces of muscular tissue elasticity

Question 2

Active expiration

Answer 2

Expiration arising from muscular activity

Question 3

Spirometer

Answer 3

Device used to measure respiratory volume

Question 4

Manometer

Answer 4

Device used for measuring air pressure differences

Question 5

Resting tidal volume

Answer 5

AKA: Expiratory reserve volume

The volume of air remaining wothin the lungs after quiet tidal expiration

Question 6

Inspiratory reserve volume

Answer 6

The volume of air that can be inhaled after a tidal inspiration

Question 7

Expiratory reserve volume

Answer 7

AKA: Resting lung volume

The volume within the lungs after quiet tidal expiration

Question 8

Residual volume

Answer 8

In respiration, the vilume of air remaing after a maximum exhalation

Question 9

Vital capacity

Answer 9

The total vomume of air that can be inspired after a maximal expiration

Question 11

Inspiratory capacity

Answer 11

The maximum inspiratory volume possible after tidal expiration

Question 12

Expiratory capacity

Question 13

Total lung capacity

Answer 13

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

Question 14

Dead air space

Answer 14

The air within the conducting passageways that cannot be involved in gas exchange

Question 15

Alveolar pressure

Answer 15

Air pressure measured at the level of the alveolis in the lung

Question 16
