A Lung Model Kit is a hands-on educational tool that demonstrates the anatomy and function of the human lungs and respiratory system. It is widely used in classrooms, science labs, and homes to teach students about the mechanics of breathing, lung structure, and how air flows in and out of the lungs. This model typically includes components to illustrate how the lungs expand and contract, making it an engaging, interactive way to understand respiratory biology.
