Constructing a lung model is an excellent way to learn about the respiratory system and how the lungs function.
The lungs are respiratory organs that are vital to the breathing process and necessary to acquire life giving oxygen.
They provide a place for gas exchange between air from the outside environment and gases in the blood.
When we breathe, our diaphragm contracts and expands. When we inhale, our diaphragm contracts to make room for your lungs, which fill up with air the way balloons do when we blow them up.
The model demonstrates this action when we pull down on its latex bottom.
When we exhale, our diaphragm expands, forcing the air out of our lungs.
The muscles of the rib cage, which protect the lungs, are also used in respiration, allowing the lungs to fill up with air. The main purpose of respiration is the intake of air, which contains oxygen, an element vital to our survival, and the removal of the waste product carbon dioxide.
