1
When compared with normal breathing, what happened to the mean tidal volume when the volunteer breathed through the tube?
A)It increased.
B)It stayed about the same.
C)It decreased.
2
Which of the following do you think would be increased by breathing through the plastic tube?
A)The alveolar volume.
B)The anatomical dead space.
C)The vital capacity.
3
Do you think that breathing through the plastic tube changed the metabolic rate of the volunteer?
A)Yes, it significantly increased the metabolic rate.
B)No, it did not significantly increase the metabolic rate.
C)Yes, it significantly decreased the metabolic rate.
4
If breathing through the plastic tube had little effect on the volunteer’s metabolic rate, over the long term would alveolar ventilation:
A)increase?
B)decrease?
C)stay about the same?
5
If the tidal volume is 375 mL and the anatomical dead space is 150 mL, what is the alveolar ventilation?
A)0 mL.
B)150 mL.
C)225 mL.
D)375 mL.
6
If the tidal volume is 375 mL and the anatomical dead space is increased to from 150 mL to 350 mL, what is the new alveolar ventilation?
A)375 mL.
B)350 mL.
C)200 mL.
D)25 mL.
7
If the tidal volume is 375 mL, and the anatomical dead space is increased to from 150 mL to 375 mL, how much fresh air enters the alveoli, i.e., what is the new alveolar ventilation?
A)0 mL.
B)150 mL.
C)225 mL.
D)375 mL.
8
If the metabolic rate is not changed by breathing through the tube which of the following variables must be changed to maintain alveolar ventilation?
