  20. non-musical, discontinuous popping sounds during inspiration caused by delayed reopening of the airways head on chest auscultation

  21. measure of the force required to expand or inflate the lungs
    compliance
  22. short, fine hairs that provide a constant whipping motion that serves to propel mucus and foreign substances away from the lungs towards the larynx
