Human Lungs Model in Jar

Human Lungs Model in Jar – Breathing Mechanism Demonstration for Biology & STEM Labs | Manufactured by Samtech Instruments

Samtech Instruments, a leading Indian manufacturer of science education models since 2002, presents the Human Lungs Model in Jar — an interactive STEM teaching aid designed to demonstrate the working of human lungs and breathing mechanism.

This model is ideal for biology classrooms, science laboratories, and STEM learning environments, helping students understand inhalation and exhalation through a simple hands‑on demonstration.

What Is the Human Lungs Model in Jar?

The Human Lungs Model in Jar is a working respiratory system demonstration that shows how lungs expand and contract during breathing. The model uses balloons to represent lungs, a tube as the trachea, and a flexible membrane at the bottom representing the diaphragm.

When the diaphragm membrane is pulled downward, the balloons inflate, demonstrating inhalation. When pushed upward, the balloons deflate, demonstrating exhalation. This clearly explains how pressure changes inside the chest cavity control breathing.

Enclosed inside a transparent jar, the model allows easy observation, making it ideal for classroom demonstrations and STEM learning activities.

The Model Typically Includes

• Transparent jar chamber for clear observation

• Balloon lungs representation

• Trachea and bronchial tube structure

• Flexible diaphragm membrane at bottom

• Airtight lid with tube assembly

• Durable classroom demonstration base
