At the most basic, the physiology of human fluid metabolism splits into the extracellular fluid compartment and the intracellular fluid compartment. Even with that separation, there is a constant exchange of water, ions, and non-ionized substances between the compartments and subcompartments. [1]

Basic compartments



At this point in the diagram, we only distinguish between plasma and interstitial fluid, not urine, lymph, sweat, and other fluids. It is practical to devide by compartments.[2]

Substance Extracellular volume Intracellular volume
Sodium 135-145 mEq/L 10-20 mEq/L
Potassium 3.5-5.0 mEq/L 130-140 mEq/L
Chloride 95-105 mEq/L
Bicarbonate 22-26 mEq/L
Glucose 90-120 mg/dL
Calcium 8.5-10 mg/dL
Magnesium 1.4-2.1 mg/dL 20-30 mEqL
Urea nitrogen 10-20 mg/dL 10-20 mg/dL
