    OverviewThree current exchange systemsCountercurrent exchange in biological systemsCountercurrent exchange in industry and scientific researchSee alsoExternal links

    Countercurrent exchange along with cocurrent exchange and contra-current exchange comprise the mechanisms used to transfer some property of a fluid from one flowing current of fluid to another across a barrier allowing one way flow of the property between them. The property transferred could be heat, concentration of a chemical substance, or other properties of the flow. When heat is transferred, a thermally-conductive membrane is used between the two tubes, and when t
