in the cells
extracellular fluid









































extracellular fluid (ecf) denotes all body fluid outside the cells of any multicellular organism. total body water in healthy adults is about 60% (range 45 to 75%) of total body weight; women and the obese have a lower percentage than lean men. about two thirds of this is intracellular fluid within cells, and one third is the extracellular fluid. the main component of the extracellular fluid is the interstitial fluid that surrounds cells.

they then proceed by analyzing the consequences of these two claims at the level of the smallest circulatory tubules (capillaries, alveoli, etc.). experimentally, the volume contained in those smallest tubules is constant across a wide range of masses. because fluid flow through a tubule is determined by the volume thereof, the total fluid flow is proportional to the total number of smallest tubules. thus, if denotes the basal metabolic rate, the total fluid flow, and the number of minimal tubules,formula_1.circulatory systems do not grow by simply scaling proportionally larger; they become more deeply nested. the depth of nesting depends on the self-similarity exponents of the tubule dimensions, and the effects of that depth depend on how many "child" tubules each branching produces. connecting these values to macroscopic quantities depends (very loosely) on a precise model of tubules. web show that, if the tubules are well-approximated by rigid cylinders, then, in order to prevent the fluid from "getting clogged" in small cylinders, the total fluid volume satisfiesformula_2.because blood volume is a fixed fraction of body mass, formula_3.
