WebAvian lungs are relatively compact, with a bird's lungs being approximately 50% as large as the lung of a mammal of a similar size. The lungs are unlobed and do not have the capacity to expand due to the close arrangement between the finite gas exchange structures, i.e.the air capillaries and blood capillaries and scanty connective tissue.

WebDec 11, 2015 · Birds have evolved one of the most complex respiratory systems of all animal groups. They ventilate their lungs by means of air sacs, structures that are unique to birds (and possibly dinosaurs). The air sacs do not play a direct role in gas exchange, but they store air and act like a bellows, pushing air into the lungs. Therefore, the lungs ...

WebHowever, some birds lack the neopulmonic parabronquio, as it is the case of the penguins and some races of ducks. Singular birds, such as canaries and gallinaceae, have a neopulmonic parabronchus developed where 15% or 20% of the gas exchange is given. WebThe gas exchange system in birds exhibits many unique features that endow them with the enhanced capacity for oxygen transport that is believed to underlie the evolution of the increased cardiorespiratory performance required to support flight.
