Which outcome results when the operculum fails to close during a ram ventilation attempt in fish?

💡 Explanation

When the operculum fails to close, countercurrent exchange efficiency is compromised because the water flow is not properly directed across the gill filaments, reducing effective oxygen extraction from the water. Therefore, reduced oxygen extraction results, rather than accumulation, equilibrium disruption, or anaerobic metabolism increase, which address unrelated process failures.
