02/19/17 page 2 Experiment Results Predict Question: Predict Question 1: What effect will adding more surfactant have on these lungs? Predict Question 2: What will happen to the collapsed lung in the left side of the glass bell jar if you close the valve? Stop & Think Questions:Why did the sequential additions of surfactant change this lung system? What happened to the left side of the bell jar when the valve was opened? Did the collapsed left lung reinflate?

02/19/17 page 7 Review Sheet Results 1. What effect does the addition of surfactant have on the airflow? How well did the results compare with your prediction? 2. Why does surfactant affect airflow in this manner? 3. What effect did opening the valve have on the left lung? Why does this happen? 4. What effect on the collapsed lung in the left side of the glass bell jar did you observe when you closed the valve? Howwell did the results compare with your prediction? 5. What emergency medical condition does opening the left valve simulate? 6. In the last part of this activity, you clicked the Reset button to draw the air out of the intrapleural space and return thelung to its normal resting condition. What emergency procedure would be used to achieve this result if these were the lungsin a living person? 7. What do you think would happen when the valve is opened if the two lungs were in a single large cavity rather thanseparate cavities?
