Lung Demonstration Model
Product Code : JA-AM-204
The Lung Demonstration Model (SKU JA-AM-204) is the classic bell jar apparatus for showing how breathing works. Two rubber balloons represent the lungs inside the jar, a rubber stopper carries the airway, and a thin rubber diaphragm closes the base. Pulling the diaphragm down makes the balloons inflate, as in inhaling, and pushing it in makes them deflate, as in exhaling. JaincoLab makes this lung demonstration model for school biology.
Specifications
The model measures 17 x 17 x 20 cm and consists of a bell jar, two rubber balloons, a rubber stopper and a thin rubber diaphragm at the base of the jar, which is moved to show inhaling and exhaling.

Applications of the lung demonstration model
The model is used to show that breathing is driven by pressure changes: when the diaphragm moves down the volume in the jar rises, pressure falls and air flows into the balloons, and the reverse happens on exhaling.
