Abstract：
: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.
