Respiratory System Model
Product Code : SCL-PLE-11666
Quick Answer: The Respiratory System Model is a bell-jar breathing model, 150 mm in diameter and 200 mm high, with two elastic lungs on a Y-shaped trachea and a rubber diaphragm pulled by a handle.
Last updated: 19 October 2026
Key Features
- Transparent polymer bell jar represents the chest cavity.
- Two elastic lungs connected through a Y-shaped tube with airtight seals.
- Flexible rubber diaphragm with a pull handle.
- Shows breathing as a change in pressure inside the chest.
Technical Specifications
| Specification | Value |
|---|---|
| Size | 150 mm diameter x 200 mm height |
| Chest cavity | Transparent, impact-resistant polymer bell jar |
| Lungs | Two elastic lung analogues |
| Trachea | Y-shaped tubing with airtight seals |
| Diaphragm | Flexible rubber membrane with pull handle |
How It Is Used
Pulling the diaphragm down enlarges the space inside the jar and lowers the pressure, so air flows in through the tube and the lungs inflate. Pushing it back raises the pressure and the lungs empty. The model links breathing to the pressure–volume relationship of Boyle’s law.
Frequently Asked Questions
How does the Respiratory System Model show breathing?
Pulling the rubber diaphragm lowers the pressure in the bell jar, so air enters through the Y-shaped tube and both lungs inflate; releasing it lets them deflate.
What size is the Respiratory System Model?
It measures 150 mm in diameter and 200 mm in height.
