Balloon Lungs Demo

Code Number: 11A10.15

Demo Title: Lung

Condition: Excellent

Principle: Physiology

Area of Study: Physiology, Biology

Equipment: Lung Model and Edmund Scientific 30 Inch Balloons.

Procedure: 

Place new balloons on the "esophagus".  Secure the top plate/lungs in place on the "body cavity" with nylon thumb screws.  Place a new "diaphragm" onto the bottom opening and then attach the legs.  DO NOT stretch the diaphragm tightly, but rather leave it loose enough so that you can easily grab it in the middle.  As you then pull down on the diaphragm, the lungs should inflate (inhale).  As you push up on the diaphragm the lungs should deflate (exhale).
