Last updated: August 2026
Quick answer: The Human Lung Model in Bell Jar is supplied by Science Lab Supplies as part of its Human Respiratory System range, manufactured and exported from Jining City, Shandong Province, China for schools, colleges and laboratory buyers.
This simple model demonstrates the functioning of lungs for students. This depicts how the lungs are emptied and filled with air by the relaxation and contraction of the diaphragm muscle. Two balloons attached to a Y-tube simulate the lungs.
The chest cavity is a bell jar with open top and stout rubber sheet that acts as the diaphragm. As the diaphragm is pulled downward, the atmospheric pressure is lowered inside the chamber, causing the lungs to expand and take in air. When the diaphragm is released, the lungs deflate.
