Circular breathing

The respiration cycle

The inhaled air, in red in the animated drawing, goes from the nasal cavity into the lungs through the trachea. The expired air, in blue, sent forth by the lungs, goes backwards from the trachea heading for the mouth.

When the base of the tongue lifts up and touches the palate, the pressure inside the mouth increases so that the air present inside is forced toward the reeds.
