Abstract:
This paper determines the distribution of bioelements such as zinc and copper in the membranes of the placenta, i.e. the chorion and the amniotic sac. The study material was taken in the course of labour from women with normal pregnancy. In the material taken, the level of microelements was determined by nuclear absorption spectrometry. In the chorion a higher level of zinc and copper was found in comparison with the amniotic sac.
