Which outcome results when a fish's gills' countercurrent flow is disrupted by mucus accumulation following parasitic infection?

💡 Explanation

When mucus buildup on the gills disrupts countercurrent exchange, diffusion rate of oxygen into the bloodstream falls because the oxygen gradient isn't maintained as effectively. Therefore decreased oxygen uptake efficiency results, rather than increased saturation, reduced ammonia excretion, or enhanced carbon dioxide removal, which depend more on respiratory and metabolic rates.
