In the lung breathing system model, the balloon at the bottom serves as the diaphragm muscles and the two balloons inside serves as the left and right lung. Pulling the bottom balloon represents inhalation in which the diaphragm muscles will contract. It increases the volume of the container resulting to lower air pressure of the two balloons. Since air pressure of the two balloons lowered, the air outside will move towards or inside the two balloon and making it to expand.
When you return the bottom balloon to its original position in represents exhalation in which the diaphragm muscles will relax and the two balloons decreases in size.
