This is a simple model of a lung system consisting of a chamber with a membrane at the bottom and a tube at the top that branches into two tubes leading to two balloons. In the inhalation step, the membrane pulls downward, the thoracic volume increases, and the pressure decreases as a consequence of Boyle's law (); therefore air enters the lung. In the exhalation process, the membrane moves upward and air is expelled.
