he balloon represents your elastic lung.
The tubing represents your breathing airways.
The plunger represents the diaphragm.
The wall of the syringe represents the chest wall.
Please examine the following illustrations in your e-book, which will assist you in building a solid foundational understanding.

3. If you push the plunger all in, cover the hole in the syringe with one finger and slowly pull down on the plunger. (3 pts)
What would happen to the balloon (inflate, deflate, no change)? ______________________
Explain the scientific principles, such as Boyle's law, that are at play in this process. How does this result in the inflation of the balloon?__________________________________________________________________________________________________________________

4. Uncover the hole! (3 pts)
What happens to the balloon (inflate/deflate/no change)? __________________________
Explain your observation! _________________________________________________________________________________________
5. How the situation in question 4 is analogous to creating a pneumothorax and a collapsed lung in a person. Discuss the implications of subatmospheric pressure in this context.
