The Renal Countercurrent Mechanism
The function of the kidney is to regulate the composition of the blood plasma. The plasma is the part of the blood that remains when the cells have been removed. We shall consider only the regulation of the Na+ content of the blood plasma, but the reader should keep in mind that the kidney is actually regulating the concentrations of many other substances at the same time.
