Human Lungs Model in Jar
Product Code : SCL-PLE-11468
Quick Answer: The Human Lungs Model in Jar is a working biology model in which two balloons inside a transparent jar inflate and deflate as a rubber diaphragm is pulled and pushed, showing how breathing works.
Last updated: 19 October 2026
Key Features
- Transparent plastic jar so the balloons can be watched.
- Two rubber balloons represent the lungs, joined to a tube representing the trachea.
- Flexible rubber sheet across the base acts as the diaphragm.
- Operated by hand; no power needed.
Technical Specifications
| Specification | Value |
|---|---|
| Components | Jar, two balloons (lungs), tube (trachea), rubber sheet (diaphragm) |
| Materials | Transparent plastic jar, rubber balloons, flexible membrane |
| Operation | Manual |
How It Is Used
Pulling the rubber sheet downward increases the space inside the jar, and the balloons fill with air to show inhalation. Pushing the sheet back up makes the balloons deflate, showing exhalation and the part the diaphragm and air pressure play in breathing.
Frequently Asked Questions
How does the Human Lungs Model in Jar show breathing?
When the rubber sheet (diaphragm) is pulled down, the two balloons (lungs) inflate to show inhalation; when it is pushed up, they deflate to show exhalation.
