| 3 . |
|
Refer to Activity 2: Examining the Effect of Changing Airway Resistance on Respiratory Volumes. What happened to the FEV1 (%) as the radius of the airways was decreased?
|
|
| 4 . |
|
What is the FEV1 (%)?
|

|
| 6 . |
|
How would you explain the effects of surfactant on airflow?

Refer to Activity 4: Investigating Intrapleural Pressure.
What happened to the lung in the left side of the bell jar, when the valve was opened?
|
|
| 9 . |
|
How did the pressure in the left lung differ from that in the right lung, after the valve was opened? Choose all that apply:
|
|
| 10 . |
|
What caused the left lung to deflate? Choose all that apply:
|
|
| 11 . |
|
How did the total airflow in this trial compare with that in the previous trial in which the pleural cavities were intact?
|
|
| 12 . |
|
What would happen if the two lungs were in a single large cavity instead of separate cavities?
|
|
| 13 . |
|
What happened to the deflated lungs?
|
|
| 14 . |
|
Explain why the lungs do not inflate when the valve is closed.
|
|
| 15 . |
|
Why did the lung function in the deflated (left) lung return to normal after you clicked Reset?
|
|
| 16 . |
|
Refer to Activity 5: Exploring Various Breathing patterns. What happened to the PCO2 during rapid breathing?
|
|
| 17 . |
|
How would you explain a decrease in PCO2during rapid breathing?
|
|
| 18 . |
|
Refer to Activity 5: Rebreathing. What happens to PCO2 over the course of the rebreathing activity?
|
|
| 19 . |
|
Refer to Activity 5: Breath Holding. What happened to the PCO2 during breath holding?
|
|
| 20 . |
|
Following breath holding, what happened to the breathing pattern when normal respirations resumed?
