Renal physiology seeks to understand the importance of the water content and the solute composition of body fluid compartments and the mechanisms used by the kidneys to regulate them. All substances in the body fluids come from either intake or metabolism and are eliminated by either excretion or metabolic consumption. To maintain relatively constant concentrations of these substances in the body, the total amount taken in and produced must equal the total amount excreted and consumed. Therefore, the regulation of body fluid composition is accomplished by adjusting the output of water and electrolytes to match their input, such that both water and electrolyte balances are maintained.
