Which outcome affects a bird’s flight efficiency when damaged air sacs cause reduced oxygen flow?

💡 Explanation

When air sacs are damaged and oxygen flow decreases during flight, the bird experiences increased anaerobic respiration as muscle tissue lacks sufficient oxygen, leading to increased lactic acid build up and premature muscle fatigue during flight. Therefore increased anaerobic fatigue results, rather than solubility, respiration, or countercurrent exchange which require differing mechanisms altering gas gradients blood chemistry.
