Which outcome results if the avian parabronchial lung's crosscurrent flow is disrupted?

💡 Explanation

Reduced oxygen extraction occurs due to inefficient gas exchange caused by disrupted crosscurrent exchange; because blood and airflows are no longer perpendicular therefore optimal, which limits oxygen absorption, rather than enhancing other functions such as CO₂ waste.
