ECF 1/3 ICF2/3 interstitial 2/3 of ECF** plasma 1/3 of ECF TBW is 1/3 ECF+ 2/3 ICF as I remember ECF-plasma volume=interstitial fluid some books say 2/3 and some books say 3/4 of ECF for interstitial fluid and you can ONLY measure it indirectly! [I prefer 2/3 because of the i in ICF and the i in interstitial] {Talk about playing with numbers}
