Which outcome occurs when a fish passively ventilates?

💡 Explanation

Pressure from swimming movements drives water across the gills using ram ventilation; countercurrent exchange then enables efficient oxygen absorption, because the operculum area receives the most oxygen-rich water. Therefore, oxygen uptake improves there, rather than laminar flow disrupting any efficiency.
