Birds have very different lungs than mammals because birds don't have a diaphragm. Air is pulled in by expansion of the rib cage and is drawn first into the lung, which instead of being arranged in blind-ended sacs (alveoli) are arranged into tubes. A second draw pulls the air from the lungs and into air sacs throughout the body cavities where additional oxygen is pulled from the air. The air is then expelled from the air sacs through the pharynx back into the atmosphere.
