Study Notes
Body Fluid Distribution
-
Body fluids are divided into two main compartments: intracellular fluid (ICF) and extracellular fluid (ECF).
-
ICF represents approximately two-thirds of total body water and is found within cells.
-
ECF comprises one-third of total body water and is found outside cells, including interstitial spaces and blood vessels.
-
ECF is high in sodium, calcium, and chloride, with moderate bicarbonate levels and low potassium levels.
-
ICF contains low levels of sodium, calcium, chloride, and bicarbonate, but high levels of potassium.
