Reference no: EM132408220

Anatomy respiratory system/ Bell jar method balloons represented the lungs. Total of 3 questions here. The questions are as follows:

1. Apply upward pressure to the diaphragm. This represents how the diaphragm looks when relaxed. What has happened to the pressure of the system ( has it increased or decreased)? What happened to the volume of the lungs?

2. Now slowly release the diaphragm, this represents the diaphragm flattening out as it contracts, what is happening to the pressure as you release the diaphragm? What happened to the volume of the lungs?

3. If your bell jar model has a rubber stopper in the top , you can use it to demonstrate the effects of pneumothorax on lung tissues , it's generally caused by a tear in the pleural membrane that allows air to enter the pleural cavity . With the diaphragm flat and the lungs ( balloons) inflated loosen the stopper , what happens to the lungs & why?
