Tidal volume
Inspiration
Expiration
9
The process of continuously moving air in and out of the lungs is _____.
Pulmonary ventiltion
Breathing
Respiration
Inhalation and exhalation
10
Why is residual volume important ?
It allows breathing to occur continuously
it allows oxygen between inspiration and expiration.
It doesn't allow gas exchange to occur continuously
it allows gas exchange to occur inspiration and expiration
11

True
False
12
___ is the process by which oxygen and carbon dioxide are transported to and from the lungs.
inspiration
pulmonary ventilation
expiration
respiratory gas transport
13
Identify four nonrespiratory air maneuvers.
Vital capacity, residual vol inhaltion hering- breuer reflex
Cough, sneeze, hiccup and yawn
Pulmonary vent. , external res Mechanoreceptors tidal volume
Central CR, Dynamic lung vol, static lung vol, internal res.
14
What is the respiratory system’s main job?
Gas exchange
Measure the overall expiratory power of the lungs
To prevent overinflation of the alveolar sacs.
Control Breathing
15
Which process does gas exchange occurs between the alveoli in the lungs and pulmonary blood?
expiration
external respiration
internal inspiration
inspiration
16
when intrapulmonary pressure and the atmospheric pressure expands during inspiration it ______
Both A and C
As the lungs expand the IP falls below AP.
The dome-like diaphragm muscle contracts downward
When the IP is lower than the AP, a vacuum is created.
17
The overall expiratory power of the lungs are called _______.
Forced expiratory volume in 1 second forced vital capacity.
Expiration
Respiration
External expiration
18

Nothing can determine it
dynamic lung volume
Lung capacity
Static lung volume
20
breathing is controlled by the inspiratory and expiratory breathing centers of the brain
True
False
21
What is another name for inspiration?
Exhilation

Central chemoreceptors
Peripheral chemoreceptors
Mechanoreceptors
Pulmonary ventilation
23
Why do women have higher respiratory rates than men?
Because men don't breath
Because they have bigger lung capacity than men
Because women breath less then men
Because they have Smaller lung capacity than men
24
