← Nature & AnimalsWhich outcome occurs when disruptions to seawater flow reduce flow reaching fish gil filaments?
A)Decreased oxygen diffusion into the blood✓
B)Increased salt excretion from the gills
C)Elevated carbon dioxide release to plasma
D)Enhanced nutrient absorbance from water
💡 Explanation
Reduced water flow impairs the *countercurrent exchange* system because oxygen absorption efficiency drops significantly where capillary blood and water flow interaction plummets; thus, lower oxygen perfusion results from reduced gradient effectiveness rather than improved waste elimination.
