Fluid Balance

Meaning

Fluid balance, or water homeostasis, refers to the precise equilibrium between the volume of water intake and the volume of water output in the body, maintaining the appropriate concentration of electrolytes and non-electrolytes in the intracellular and extracellular compartments. This physiological state is crucial for cellular function, blood pressure regulation, and the optimal delivery of hormones and nutrients throughout the circulatory system. Disruptions to this balance can profoundly affect cellular metabolism and neurological function.
