Human Lung Demonstration Model Manufacturer,Supplier and Exporter in India
Product Code : ILS-HSM-11049
Indian Lab Suppliers supplies the Human Lung Demonstration Model (Product ID: 11049) as part of its human system models range. It is a bell-jar model in which two balloons inflate and deflate as a rubber diaphragm is moved, showing how breathing works.
Quick Answer
Two rubber balloons (the lungs) hang from a rubber stopper inside a bell jar (the chest cavity), with a thin rubber sheet across the bottom as the diaphragm. Pulling the sheet down enlarges the space in the jar and lowers the pressure, so air flows in and the balloons inflate, as in inhalation. Pushing it back up raises the pressure and the balloons collapse, as in exhalation. The model measures 17 × 17 × 20 cm. Please confirm whether the bell jar is glass or plastic at quotation, and handle a glass jar with care.
