Title: The Respiratory System Lab Report
Post by: jtownsell on Mar 6, 2015
I am currently stuck at work and I do not have the material to complete this lab any and all help greatly appreciated.

1. When you pushed the diaphragm up what change occurred in chest cavity pressure? Explain how this change in chest cavity pressure affected the lungs.

2. When you pulled the diaphragm down what change occurred in chest cavity pressure (think about what changes in pressure occur during inspiration)?  Explain how this change in chest cavity pressure affected the lungs.

3. Surface Area =
Estimated Vital Capacity =

4b. From your graph describe the correlation between height and vital capacity. (See attachment 3a)

5. From your graph describe the correlation between height and vital capacity.

6. From your graph describe the correlation between smoking and vital capacity.

7. The correlations shown by the graphs of the class data may be different to what you expected.   Provide reasons that may explain why our class data did not fit the expected outcome of the experiment.  (Make sure you say what you expected the result to be, what the data showed, and why they may be different.)

8. Very few people will have their VC exactly match their predicted value. Give reasons as to why this may be so.
