none of the above
Question 2
Question

Answer
-
tidal volume; 1200

Answer
-
500 mm Hg.
-
560 mm Hg.
-
660 mm Hg.
-
760 mm Hg.
Question 6
Question

nose, pharynx, larynx
-
trachea and the bronchi

all of the above
Question 7
Question
All of the following are regulated processes associated with the functioning of the respiratory system except
Question 8
Question
Dalton's law is also known as
Question 9
Question
Temperature is the measurement of the motion of molecules
Question 10
Question
The largest amount of air that can enter and leave the lungs during respiration is termed total lung capacity (TLC)
Question 11
Question
Residual volume (RV) is the volume remaining in the respiratory tract after maximum expiration
Question 12
Question
The temporary cessation of breathing is termed apnea
Question 13
Question
It is not possible to exhale all of the air from your lungs
Question 14
Question
The ability of the lungs and thorax to stretch, referred to as [blank_start]compliance[blank_end], is essential to normal respiration.
Question 15
Question
Intrapleural pressure is always less, or negative with respect to alveolar pressure. The difference is called the [blank_start]transpulmanory[blank_end] [blank_start]pressure[blank_end].
Question 16
Question
Tidal volume multiplied by the respiratory rate yields the [blank_start]total[blank_end] [blank_start]minute[blank_end] [blank_start]volume[blank_end].
Question 17
Question
The constant alternation between inspiration and expiration is called the [blank_start]respiratory[blank_end] [blank_start]cycle[blank_end].
Question 18
Question
The basic rhythm of the respiratory cycle of inspiration and expiration seems to be generated by the [blank_start]medullary[blank_end] [blank_start]rhythmicity[blank_end] [blank_start]area[blank_end].
Answer
-
medullary
-
rhythmicity
-
area
Question 19
Question
The term that means the same thing as breathing is
Answer
-
gas exchange
-
respiration
-
inspiration
-
pulmonary ventilation
Question 20
Question
Which of the following does not occur during inspiration?
Question 21
Question
A young adult male would have a vital capacity of about
Answer
-
500 mL
-
1200 mL
-
3300 mL
-
4800 mL
Question 22
Question
The amount of air that can be forcibly exhaled after expiring the tidal volume is knows as the
Question 23
Question
Which one of the following is correct?
Answer
-
VC = TV - IRV + ERV
-
VC = TV + IRV - ERV
-
VC = TV + IRV x ERV
-
VC = TV + IRV + ERV
Question 24
Question
Air in the pleural space of the thoracic cavity is called a pneumothorax
Question 25
Question
A deficiency of surfactant in premature infants is called SIDS

[blank_start]Physiologic dead space[blank_end]: increased in emphysema
[blank_start]Oxygen pressure[blank_end]: Po2
[blank_start]Surfactant[blank_end]: reduces surface tension in lungs
[blank_start]Apneusis[blank_end]: cessation of breathing
[blank_start]Chemoreceptors[blank_end]: sensitive to changes in arterial CO2 and pH
