This is plain wrong and is NOT how air flows through the avian respiratory system.

There is no difference between a 1st and 2nd breathing cycle.

During inhalation air splits at the end of the mesobronchus and ~1/2 enters the posterior air sacs whilst the rest passes through the lungs and into the anterior air sacs.

During exhalation air from the posterior air sacs pass through the lungs and exits via the trachea whilst air from the anterior air sacs exit directly via the trachea.

@caveatempt0r Thanks for your input, I'm sure you are right.

Thanks for this, this was a much better explanation than I found in my book or heard in class.

google for Airflow and respired gases within the lung-air-sac system of birds to get a paper by J.H Brackenbury

Or Google for bird lung and select the people.eku.edu/ritchisong/bird­respiration page. Its usually the first hit.

I don't understand why my professor had such a difficult time getting this concept across geez
