# COUNTER CURRENT MECHANISM

Answer 2

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

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.

Countercurrent multiplication moves sodium chloride from the tubular fluid into the interstitial space deep within the kidneys. ...

As a result, water moves passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space, until it reaches equilibrium.
