Countercurrent exchange Definition:
In fishes, the efficiency of gas exchange is maximized by countercurrent exchange, the exchange of a substance or heat between two fluids flowing in opposite directions.

Countercurrent exchange Notes:
Countercurrent exchange is a mechanism occurring in nature usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other. The flowing bodies can be liquids, gases, or even solid powders, or any combination of those. For example, in a distillation column, the vapors bubble up through the downward flowing liquid while exchanging both heat and mass. In biology this is seen in fish where the efficiency of gas exchange is maximized by countercurrent exchange
