Before the advent of isotopes in biological research, the elements making up the bodies of adult animals were presumed to be more or less static, being replaced only slowly. Food substances, on the other hand, were thought to be rapidly used up and their residues excreted. The use of isotopes soon indicated that the elements comprising all parts or the body had a rate of turnover which varied somewhat, but was often much higher than expected. Radioactive calcium has become available in recent years and has helped to elucidate further the behaviour of calcium in metabolism.
