About This Product
In a respiratory system lesson the teacher names each part of the jar, then pulls the diaphragm sheet down so the class can watch the balloons fill, and lets it return so they empty again. Linking what students see to pressure inside the chest cavity makes inhalation and exhalation easy to explain, and the model also works well at science exhibitions.
Frequently Asked Questions
What happens when the diaphragm of the Human Lungs Model in Jar is pulled down?
The balloon lungs inflate, representing inhalation. Releasing the diaphragm upward lets them deflate, representing exhalation. The movement changes the air pressure inside the jar, which is what moves the air.
