This user-friendly lung model shows in a very clear way what happens when we breathe in and out.
With a quick pull on the plastic membrane, which represents the diaphragm muscle, the pressure in the bell is reduced and air is sucked into the two lung-shaped bags, which represent the lungs.
Release the diaphragm and the pressure on the “lungs” increases and the air is forced out.
