Lung Apparatus
Product Code : EL-BLE-13120
Eduscope India is a leading Lung Apparatus
Quick Answer: The Lung Apparatus is a breathing demonstration model that uses two balloons as lungs and a rubber sheet as the diaphragm to show how breathing works.
Construction and Features
Part of EduScope India's biology lab equipment range, this model uses two balloons to represent the lungs and a rubber sheet to represent the diaphragm. Pulling the rubber sheet downward creates negative pressure within the chamber, causing the balloons to expand, and releasing the rubber sheet deflates the balloons again, demonstrating the mechanics of breathing through diaphragm contraction and relaxation.
A Human Biology Teaching Aid
As part of a human body model kit for school biology lessons, the Lung Apparatus gives students a simple, hands-on way to visualise respiratory mechanics that is difficult to show with diagrams alone.
