Model of Diaphragm and Lungs Using Bottle and Balloons

Today we built a model to illustrate how the diaphragm helps us breathe. The bottle represents the chest cavity. The green balloon at the neck of the bottle represents the lungs and the yellow balloon stretched over the cut off end of the bottle represents the diaphragm. When the diaphragm balloon is pulled outwards the lung balloon fills with air then when the diaphragm balloon is released the lung balloon deflates.
