This is how are lungs operate. Inside our bodies, at the base of our lungs there is a membrane called the diaphragm. When you inhale, your diaphragm contracts and flattens out, increasing the volume and decreasing the pressure in your chest. Because you have more room air gets sucked in through your mouth and nose and into your lungs, just like it did in the balloon, and then your lungs fill with air.
So, how exactly does the voice work? Well, as we inhale, the diaphragm muscle contracts causing the lungs to expand and air to be drawn into the lungs. As we exhale, the diaphragm will relax and move upward reducing the size of the lungs and causing air to be expelled from the lungs.
