  5. Body Fluids • Water content in body is divided into 2 compartments: 1. Extracellular fluid (ECF): (internal environment or the milieu intérieur) • Fluid outside the cells. • ECF=14 liters • 20% of body weight • Interstitial fluid between cell is 80% of ECF. • Plasma in blood is 20% of ECF • Also includes lymph, cerebrospinal fluid, synovial fluid, aqueous humor, vitreous body, endolymph, peri lymph, pleural, pericardial, and peritoneal fluids

  6. 2. Intracellular fluid (ICF): - Fluid inside the cells. - ICF=28 liters. 40% 0f body weight.
