在婴儿和儿童的生长过程中，发现了某些特征性的变化。在生命的第一年，总身体水和细胞外水的相对体积迅速减少，随后在儿童期后期，细胞外水的体积减少较小。同时，细胞外水的异质性增加。另一方面，细胞内水的体积增加了一点，在生命的第一个月，并保持或多或少的恒定从那时起。公式和列线图，这些身体水舱可以预测。最后，数据的相应变化，在总身体水分和身体比重进行了讨论。
During growth of infants and children, certain characteristic changes are found. A rapid decrease of the relative volumes of total body water and of extracellular water occurs during the first year of life, followed by a smaller decrease of volume of extracellular water later in childhood. At the same time an increased heterogeneity of the extracellular water takes place. On the other hand, the volume of intracellular water increases a little during the first months of life and remains more or less constant from then on. Formulas and nomograms from which these body water compartments can be predicted are presented. Finally, data on the corresponding changes in the total body water and in body specific gravity are discussed.
