Human Lungs Model in Jar

Product Code : SCL-M-12438

Human Lungs Model in Jar by Educational Instrument is a biology teaching model designed to demonstrate the working mechanism of human lungs, diaphragm movement, air pressure, inhalation, and exhalation. It is suitable for school biology laboratories, science classrooms, STEM learning centres, health science demonstrations, and activity-based learning sessions.

The model typically includes a transparent jar representing the chest cavity, balloon lungs, a Y-shaped airway tube representing the trachea and bronchi, and a flexible diaphragm sheet at the base. When the diaphragm is pulled downward, the balloons inflate to show inhalation; when released upward, the balloons deflate to show exhalation. This makes the model highly useful for explaining respiratory mechanics through direct observation.

Product Description

The Educational Instrument Human Lungs Model in Jar helps students understand how the respiratory system works using a simple and practical demonstration. The transparent jar allows learners to clearly observe the movement of the balloon lungs during air pressure changes inside the chamber.

Teachers can use this model to explain the function of the lungs, trachea, bronchi, diaphragm, chest cavity, air pressure, and breathing cycle. It supports visual and hands-on learning, making it easier for students to understand how inhalation and exhalation happen inside the human body.

This model is ideal for biology practicals, science exhibitions, classroom demonstrations, respiratory system lessons, STEM health science activities, and introductory anatomy teaching.

How to Use Human Lungs Model in Jar

Place the Human Lungs Model in Jar on a flat classroom table.

Identify the transparent jar as the chest cavity.

Point out the balloons as the lungs.

Explain the central tube as the trachea and branching tubes as the bronchi.

Identify the flexible membrane at the bottom as the diaphragm.

Pull the diaphragm membrane gently downward.

Observe the balloons inflate, representing inhalation.

Release or push the diaphragm membrane upward gently.

Observe the balloons deflate, representing exhalation.

Explain how pressure changes inside the chest cavity help air move in and out of the lungs.

Ask students to record observations in their science notebook.

Store the model safely after use.

FAQ

Q1. What is the Human Lungs Model in Jar used for?
It is used to demonstrate the working of lungs, diaphragm movement, air pressure changes, inhalation, and exhalation.

Q2. Is this model suitable for school biology laboratories?
Yes, it is suitable for school biology labs, science classrooms, STEM activity rooms, and respiratory system demonstrations.

Q3. Which parts of the respiratory system can be explained with this model?
Teachers can explain the lungs, trachea, bronchi, diaphragm, and chest cavity using this model.

Q4. How does the model show inhalation?
When the diaphragm membrane is pulled downward, air enters through the tube and the balloon lungs inflate, representing inhalation.

Q5. How does the model show exhalation?
When the diaphragm membrane moves upward, air is pushed out and the balloon lungs deflate, representing exhalation.
