Question

a working model of lungs​

Answer 1

Answer:

The model is in the attachment.

Explanation:

The movement of the balloon matches your breathing – when you breathe in, your lungs fill with air just like the balloon inside the bottle did. That's because the diaphragm expanded making room for air inside the lung. Air goes in and out of both of your lungs at the same time. This model just represents one lung.
