In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the nephron loop of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood
vessels (the countercurrent exchanger). This relationship establishes and maintains an osmotic gradient extending from the cortex through the depths of the medulla that allows the kidneys to vary urine concentration dramatically.
