Parabronchi 气管
http://people.eku.edu/ritchisong/birdrespiration.html WebAnother way that gas exchange can happen is through cross-current exchange in which the air carrying the oxygen is moving through the respiratory structures (parabronchi), which are positined perpendicular to the movement of blood around the parabronchi. ( Figure 2.12 ).
