4. Data Analysis • What was your Tidal Volume (TV)? How does your TV compare with other students in the class who are similar to your height? Trey’s TV was 0.1 which was exactly the male average for our class. It closely compares with Ben’s TV because they are about the same height.

5. Data Analysis • Create a graph using your values and class values for Tidal Volume (Y axis) and height (X axis). Create another line on the same graph for Vital Capacity (Y axis) and height (X axis). Make sure your graph has a title, labels and key. • Use complete sentences to describe any correlation you see between the two variables, (lung volume and height) or explain why there may not be a relationship between these data.

6. Data Analysis • You and a partner should observe each other to determine your respiratory rate (breaths / min.) 12 breaths/min. • Use your respiratory rate to calculate your Minute Volume at rest: (TV  breaths/minute) = Minute Volume at rest ) .07 x 12= .84 • If you are taking shallow breaths (TV = 0.20 L) to avoid severe pain from rib fractures, what respiratory rate will be required to achieve the same minute volume? Show your work! .84/.20= 4.2 • Exposure to occupational hazards such as coal dust, silica dust, and asbestos may lead to fibrosis, or scarring of lung tissue. With this condition, the lungs become stiff and have more “recoil.” What would happen to TLC and VC under these conditions? The TLC and VC would decrease because the stiff lungs would make it harder to inhale. • In severe emphysema there is destruction of lung tissue and reduced recoil. What would you expect to happen to TLC and VC? The TLC and VC would decrease because it would make it harder to exhale. • What would you expect to happen to your Expiratory Reserve Volume when you are treading water in a lake? Explain your reasoning.
