![]() ![]() Gaseous exchange takes place in the lungs, where carbon dioxide is exchanged for fresh oxygen.īirds need a constant supply of a higher volume of oxygen than humans, and the two-directional airflow system used in human lungs and alveoli would not provide a bird with the amount of oxygen it requires to maintain its ultra-fast metabolic rate.Ī bird’s respiratory system takes up around 20 percent of their internal volume, in contrast to around 5 percent in humans, but the network of lungs and air sacs work efficiently to supply a bird with enough fresh oxygen to be able to fly and sing at the same time! In order to sustain flight, a constant supply of oxygen needs to reach a bird’s muscles and bloodstream.īut just how does a bird’s respiratory system work? Keep reading as we take a closer look at how birds breathe.Īir flows into a bird’s body through nostril-like openings on the beak, moving through the trachea, posterior air sacs, lungs, and anterior air sacs, and passes out again through the trachea. ![]() A bird’s respiratory system is somewhat different to that of a human, and needs to work efficiently, even at higher altitudes where the air has lower oxygen levels.
