Density of trunk tissues of young and medium age people.

In this study the investigations made on about 50 trunk tissue densities are described. They were performed on ten cadavers of both sexes within 24 h of the moment of death. They were 20-40 yr old. The weight of each tissue was measured on a laboratory scale and the volume by placing the tissue in a pycnometer filled with water. The density of 2/3 solid trunk tissues ranged from 1.11 to 1.20 g cm-3. The lowest mean data was obtained for a lung tissue (0.563 g cm-3). The highest density datum known from the literature was that for a compact bone: 1.892 g cm-3. The application of obtained data can be for building dummies (e.g. in experiments of car-crash simulations), as well as in the calculation of inertia values using computerized tomography images.
