1
Look at your data for vital capacity, recorded from the volunteer at rest and immediately after exercise. Did exercise:
A)significantly increase the vital capacity?
B)not really change vital capacity?
C)significantly decrease the vital capacity?
2
Look at your data for tidal volume, recorded from the volunteer at rest and immediately after exercise. Did exercise:
A)significantly increase the tidal volume?
B)not really change tidal volume?
C)significantly decrease the tidal volume?
3
If the volume of the anatomical dead space volume is about 150 mL, how much fresh air entered the alveoli during each breath when the volunteer was at rest?
A)0 mL.
B)About 325 mL.
C)About 500 mL.
D)About 550 mL.
4
If the volume of the anatomical dead space volume is not changed by exercise, how much extra air entered the alveoli due to the exercise-induce increase in tidal volume?
A)700 mL.
B)About 500 mL.
C)About 200 mL.
D)About 0 mL.
5
Exercise increased the amount of air entering the alveoli by more than 50%. What happened to the breathing rate?
A)Exercise decreased the breathing rate.
B)Exercise did not change the breathing rate.
C)Exercise increased the breathing rate.
6
Assume that the alveolar ventilation is the (mean tidal volume – 150 mL) x breathing rate. What was the alveolar ventilation at rest?
A)About 4000 mL.
B)About 5500 mL.
C)About 7000 mL.
D)About 8400 mL.
7
Do you think that the anatomical dead space is changed by exercise?
A)The anatomical dead space is significantly increased by exercise?
B)The anatomical dead space is not really changed by exercise?
C)The anatomical dead space is significantly decreased by exercise?
8
Assume that the alveolar ventilation is the (mean tidal volume – 150 mL) x breathing rate. What was the alveolar ventilation immediately after exercise?
A)About 7000 mL.
B)About 10000 mL.
C)About 12000 mL.
D)About 15400 mL.
9
Did exercise change the expiratory reserve volume, i.e., the amount of air left in the lungs after the volunteer exhaled?
A)Exercise decreased the expiratory reserve volume.
B)Exercise did not change the expiratory reserve volume.
C)Exercise increased the expiratory reserve volume.
10
After exercise, if there was less (stale) air left in the lungs after the volunteer exhaled the larger tidal volume would mean that when the volunteer took a breath:
A)more fresh air entered the alveoli and mixed with less stale air.
B)more fresh air entered the alveoli and mixed with more stale air.
C)less fresh air entered the alveoli and mixed with less stale air.
D)less fresh air entered the alveoli and mixed with more stale air.
