1. Air Sacs

   Linked via "trachea"

   The efficiency of the avian system stems from separating the processes of air movement and gas exchange. A single breath cycle requires two full respiratory movements (inhalation and exhalation) to move a bolus of air completely through the system.
   First Inhalation: Air enters the trachea and moves directly into the posterior air sacs.
   First Exhalation: Air is pushed from the posterior sacs, through the [lungs](/entries…

2. Air Sacs

   Linked via "trachea"

   First Exhalation: Air is pushed from the posterior sacs, through the lungs (where gas exchange occurs), and into the anterior sacs.
   Second Inhalation: Air moves from the anterior sacs into the cranial (cervical and clavicular sacs), while simultaneously, fresh air enters the posterior sacs.
   Second Exhalation: Air stored in the [anterior sacs](/…

4. Vocal Cords

   Linked via "trachea"

   Superior Laryngeal Nerve (SLN): Has two branches. The external branch innervates the cricothyroid muscle, which stretches and tenses the folds to raise pitch. The internal branch provides sensory innervation to the mucosa above the folds.
   Recent studies suggest that the firing rate of the RLN motor neurons during falsetto production exhibits a nearly perfect correlation ($\rho \approx 0.98$) wit…
