Expert Answer

Yes! I've done this with my students and we made it inflate and deflate and have arteries and veins working in and out of the heart model.

This project helps students understand the mechanism of breathing. It shows how the lungs inflate when the diaphragm is brought down and air is brought in and vice versa.

Question

What happens to the smaller balloons inside?

ths 130028

Community Answer

The balloons in the interior of the model will inflate when the skin at the bottom is pulled down and air is brought in, just like a real lung. Similarly, it will deflate when we let go of the skin and air is pushed out.

Question

What does each part of the constructed lung model represent?

Community Answer

In this model, the large pink straw represents the trachea or windpipe. The two green straw segments represent the bronchi. The inner balloons represent the lungs. The bottle represents the thoracic cavity and the stretched out balloon skin at the bottom represents the diaphragm.
