Air-sacs are part of the breathing system of birds. They are situated between the trachea and the lungs and even extend into some of the bones.


The presence of air-sacs allows a constant flow of air through the lungs, even when the bird is "breathing out".


This is a necessary adaptation to allow birds' high metabolic rate and to provide them with more oxygen from the air than it is possible for mammals to obtain, which they need in order to be able to release the energy for flight.
