WebThe countercurrent system maximizes the extraction of oxygen from the water and secretion of wastes. Organisms use countercurrent systems in different ways. [ An Example ] Later we will see how fishes use a countercurrent system to inflate their swim bladders, but in the gill, it is used to increase blood/water exchange. WebMar 15, 2024 · Fish gills use a design called ‘countercurrent oxygen exchange’ to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes on more oxygen.
