Avian Versus Mammalian Respiration
How do the lungs of birds differ from those of mammals?
AMammals utilize a unidirectional airflow system with air sacs and parabronchi to maximize gas exchange efficiency.
BBirds use positive pressure breathing, whereas mammals use negative pressure breathing.
CMammals use positive pressure breathing, whereas birds use negative pressure breathing.
DBirds utilize a unidirectional airflow system with air sacs and parabronchi to maximize gas exchange efficiency.
