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.
A main function of the diaphragm is to aid respiration. When the diaphragm contracts, it causes an expansion of the lungs as air is breathed in. A diaphragm impairment can cause breathing problems, as stated by MedicineNet.The thoracic cavity contains the esophagus, heart, bronchi and lungs.
