Explanation:
Fish gills use a design called 'countercurrent oxygen exchange' to maximize the amount of oxygen that their blood can pick up. ... Countercurrent oxygen exchange (shown in the figure above) means the blood flows through the gills in the opposite direction as the water flowing over the gills
