Circulatory System Working Model Explanation Video - https://youtu.be/JG-n15_qjDc

In this science exhibition project, we demonstrate the path of blood flow through the heart, lungs, and body using a creative and easy-to-make 3D working model.

This model shows how the heart pumps deoxygenated blood to the lungs, exchanges carbon dioxide for oxygen, and then sends oxygen-rich blood to the entire body.

This project is perfect for school science fairs, biology practicals, and working model competitions.
We have used color-coded water (blue for deoxygenated, red for oxygenated) and transparent pipes to clearly show blood circulation.
