answer ✔- Functional *status* of the *lungs*
[] [] [] [] [] []
- *How MUCH & how FAST GAS* can be moved into and out of
[] [] [] [] [] [] [] [] [] [] [] [] [] []
the lungs []

What is the most important factor influencing lung size and
[] [] [] [] [] [] [] [] [] []
predicted values? - Correct answer ✔*Height* [] [] [] [] [] []
the taller the person, the larger are predicted lung volumes, flow
[] [] [] [] [] [] [] [] [] []

[] [] [] []
Lung volumes and flow rates are affected typically when the BMI
[] [] [] [] [] [] [] [] [] []
is greater than: - Correct answer ✔*BMI>30*
[] [] [] [] [] [] []
as a person gains weight, lung volumes and flow rates do not
[] [] [] [] [] [] [] [] [] [] [] []
changes until the person becomes obese (BMI>30)[] [] [] [] [] []
