    Area of Science:

    • Physiology
    • Biochemistry
    • Clinical Medicine

    Background:

    • Understanding body fluid compartments and concentration units is crucial for clinical practice.
    • Existing knowledge on fluid balance and ionic composition requires clear definitions and updated concepts.

    Purpose of the Study:

    • To define and explain the clinical utility of concentration units (mole, molality, molarity, osmole, osmolality, osmolarity, osmolar gap, anion gap).
    • To describe body fluid compartments (total body water, extracellular fluid, intracellular fluid, transcellular fluid, plasma, red cell, interstitial fluid).
    • To outline physiological mechanisms of fluid balance and introduce novel concepts in interstitial physiology.

    Main Methods:

    • Definition of key terms and concepts.
    • Description of body fluid compartments and their volumes.
