Document Summary
21. 1 the balance concept: for water and electrolytes, balance means that the quantities entering the body equal the quantities leaving, water balance and electrolyte balance are interdependent, because electrolytes are dissolved in the water of body fluids. 21. 2 distribution of body fluids: body fluids are not uniformly distributed, instead, they occupy compartments of different volumes that contain fluids of varying composition. An average adult female is about 52% water by weight. The difference between the sexes is because females generally have more adipose tissues, which has little water. An average adult male is about 63% water by weight. Includes all the water and electrolytes that cell membranes enclose (63%: high concentration: potassium, phosphate, magnesium, sulfate, and protein. Includes all the fluids outside the cell (interstitial fluid plasma, lymphatic vessels) (37%: high concentrations: sodium, chloride, calcium, and bicarbonate ions, low concentration: sodium, chloride, and, low concentrations: potassium, bicarbonate magnesium, phosphate, and sulfate ions.
