GENERAL HISTOLOGY

Detailed explanation-1: -The diaphragm at the bottom of our chest moves down to create more space. As we breathe out the diaphragm raises again. The knotted balloon represents the diaphragm and the balloon inside the container represents a lung. That’s how lungs work!!

Detailed explanation-2: -The balloon at the bottom works like your diaphragm-a strong muscle that expands and contracts to cause your lungs to fill with air and then empty out again. 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.

Detailed explanation-3: –The two small balloons represents the lungs.-The big balloon represents the diaphragm.

Detailed explanation-4: -The balloons represent the lungs, the glass jar represents the thorax and a rubber sheet represents the diaphragm .

Detailed explanation-5: -Cut a square of plastic wrap large enough to cover the bottom of your bottle. Then, using your rubber bands, secure the plastic wrap around your bottle. I used two rubber bands, one when to initially secure and the other to secure the excess plastic. In our model this plastic wrap represents the diaphragm.
