The composition of body tissues is a function of the age, nutrition, state of health and physical activity of the individual. In this paper, the effects of age on the composition of healthy tissues are reviewed. Eleven soft tissues (adipose tissue, blood--whole, brain--whole, heart, kidney, liver, lung, muscle--skeletal, placenta, skin and spleen) and cortical bone are considered. Elemental compositions, mass and electron densities are tabulated for the tissues, as a function of age, from fetus to young adult. Although the compositions given here are predominantly for healthy tissues, reported changes because of dietary influences are briefly discussed.
身体组织的构成是个体年龄、营养、健康状况和身体活动的函数。本文综述了年龄对健康组织构成的影响。研究考虑了11种软组织（脂肪组织、全血、全脑、心脏、肾脏、肝脏、肺、骨骼肌、胎盘、皮肤和脾脏）以及皮质骨。文中列出了这些组织从胎儿到青年成人阶段随年龄变化的元素组成、质量和电子密度。尽管这里给出的组成主要针对健康组织，但也简要讨论了因饮食影响而报告的变化。
