Countercurrent exchange involves the transfer of heat or substances between two fluids flowing in opposite directions, maximizing diffusion efficiency.
Lo scambio controcorrente รจ lo scambio di una sostanza o di calore tra due fluidi che scorrono in direzioni opposte. Ad esempio, il sangue in una branchia di pesce scorre nella direzione opposta all'acqua che passa sopra la branchia, massimizzando la diffusione di ossigeno nel sangue e di anidride carbonica fuori da esso.
