How To Make a Model of the Lungs

Constructing a lung model is an excellent way to learn about the respiratory systemand how the lungs function. The lungs are organs that provide a place for gas exchange between air from the outside environment and gasses in the blood. Gas exchange occurs at lung alveoli (tiny air sacs) as carbon dioxide is exchanged for oxygen. Breathing is controlled by a region of the brain called the medulla oblongata.
