← Nature & AnimalsWhich outcome occurs when ventilatory collapse decreases oxygen gradient?
A)Increased aerobic respiration by tissues
B)Enhanced CO2 extraction fish gills
C)Increased oxygen extraction from water
D)Reduced oxygen extraction at gills✓
💡 Explanation
Gills rely on countercurrent exchange to maximize oxygen extraction; decreased gradient reduces differential, weakening the mechanism. Therefore, O₂ extraction decreases, resulting in less efficient gill function, rather than enhanced transfer/increased cellular respiration within the tissues.
