Many fish use countercurrent exchange in their gills to transfer oxygen from the surrounding water into their blood. This system moves water flowing across the gills, in an opposite direction to the blood flowing in gill capillaries creating the maximum efficiency of gas exchange. This flow ensures that blood is always brought near to water having a higher oxygen concentration.
