If anyone could help with these I could give some answers to other I have done. I have the first 6 answers. Thank you
Simulating Factors Affecting Respirations
The following questions refer to Activity 3: Examining the Effect of Surfactant.
7. What effect does the addition of surfactant have on the airflow?
8. Why does surfactant affect airflow?
9. Why do premature infants have difficulty breathing?
The following questions refer to Activity 4: Investigating Intrapleural Pressure.
10. What effect does opening the valve have on the left lung? Why does this happen?
11. What condition does opening the valve simulate?
12. What is the value of the pressure in the left lung when the valve is opened?
0.00
13. What happened to the total flow when the valve was opened?
14. In the last part of this activity, when the reset button was clicked, what procedure would be used with real lungs?
Simulating Variations in Breathing
The following questions refer to Activity 5: Exploring Various Breathing Patterns.
15. What was the value of the PCO2 with rapid breathing?
How does this compare to the value with normal breathing? Explain any differences.
16. What was the value of the PCO2 with rebreathing?
Explain any difference.
53.96
17. What happened to the rate of respirations with rebreathing?
Why do you think this happened? (Hint: Think about the effects of chemoreceptors in the body).
18. What was the value of the PCO2 with breath holding? Explain any difference.
19. Was there a change in the rate of respirations when the breathing was resumed?
The following questions refer to Activity 6: Comparative Spirometry.
20. What was the value obtained for the (FEV1/FVC) x 100% with “normal breathing”?
21. What effect did “emphysema breathing” have on FVC and FEV1?
22. In “emphysema breathing” which of the two values, FVC and FEV1 changed the most?
23. What effect did “acute asthma attack breathing” have on FVC and FEV1?
24. In “acute asthma attack breathing” which of the two values, FVC and FEV1 changed the most?
25. Describe the effect that the inhaler medication had on the FVC and FEV1.
26. Did the values return to “normal”? Explain.
27. During “moderate exercise breathing,” which volumes changed the most?
28. During “heavy exercise breathing,” which volumes changed the most?
