Document Summary
Body is divided into 2 major fluid compartments: Page 1 of 1: intracellular fluid compartment (icf): inside all of the cells, extracellular fluid compartment (ecf): everything outside the cells. Makes up the internal environment of the body. Interstitial fluid compartment fluid directly outside, bathing the cells. Average 70 kg person (154 lb): total body water (tbw) = 42 l (11. 1 gallons: icf = 67% of tbw, interstitial fluid compartment = 26. 4% of tbw, plasma = 6. 6% of tbw. 92% water, 8% other (proteins, ions, nutrients, gases, waste products) Colloidal solutions liquid that contains suspended substances (ie. plasma proteins like albumins, globulins, and fibrinogen) that do not settle out of solution. Volume of plasma remain relatively constant (water intake through digestive tract closely matches water loss through kidneys, lungs, digestive tract, and skin) There are large differences in ion concentrations between the inside (icf) and outside of the cell (ecf)
