← Nature & AnimalsWhich outcome occurs due reduced blood flow across fish gills lamellae?
A)Reduced oxygen diffusion efficiency✓
B)Accelerated carbon dioxide expulsion
C)Increased ammonia excretion rate
D)Enhanced countercurrent exchange mixing
💡 Explanation
With reduced blood flow, decreased residence time across lamellae lessens overall blood circulation, thereby lowering the efficacy of countercurrent exchange due less time for diffusion and thus reduces extraction. Therefore reduced oxygen diffusion results, rather than increased expulsion or higher excretion because this relies of diffusion efficiency
