Which process is directly enhanced by avian air sacs linking lungs to bones?

💡 Explanation

When birds utilize air sacs connected to their lungs and bones, unidirectional airflow is maintained because the sacs act as reservoirs. Therefore, improved oxygen uptake results, rather than waste removal, buoyancy, or sensory perception which rely on different anatomical specializations.
