A countercurrent mechanism system is a mechanism that expends energy to create a concentration gradient.

It is found widely in nature and especially in mammalian organs. For example, it can refer to the process that is underlying the process of urine concentration, that is, the production of hyperosmotic urine by the mammalian kidney.[1] The ability to concentrate urine is also present in birds.[1]

Countercurrent multiplication is frequently mistaken for countercurrent exchange, a similar but different mechanism where gradients are maintained, but not established.
