Respiratory System – Lung Model

To help us understand how our respiratory system works, we built these lung models. The plastic bottle is the chest, the ziploc bag is the diaphragm, and the balloon is the lungs. When we pull down the bag (diaphragm), the balloon (lungs) fill up.  When we push up the bag (diaphragm), the balloon (lungs) empties.
