¨Upon Inspiration... 

air flows through our nose and mouth on its way to our lungs.

¨This Collapsible Airway...

is pulled inward with each breath we take.

¨A Balance of Forces...

is maintained by dilator muscles whose function is to hold the airway open when we inhale.

¨Bernoulli’s Principle...

states that an Increased air flow through a hollow tube produces a corresponding drop in pressure.  In the case of inhalation, the forces promote collapse of the throat walls.

¨Musically Inclined...

with each breath, the pliable tissues in the throat rebound and vibrate.
