Summary: The placenta is the central organ of fetomaternal exchange,
which metabolically provides for the growth of the fetus and its membranes
as a whole. The main structural components of the human placenta develop
until the beginning of the second trimester of gestation, and continue to
grow and differentiate. The dynamics of the histomorphological development
of the placenta lasts until birth. The aim of this stereological
investigation was to analyse and compare structural components of placental
parenchyma during two periods of the 10th lunar month: from the 38th to
39th week, and in the 40th week of gestation. The results show that during
the last four weeks of gestation the trophoblast of the chorionic villi
changes the most. At the beginning of the 10th lunar month, alpha zones,
bearers of transplacental gas transport, prevail. At the end of the 10th
lunar month beta zones dominate (P<0.005). These are metabolically active
parts of trophoblast. These quantitative results of stereological analysis
have to be assumed as structural evidence of the physiological maturity of
human placenta.

Summary: The placenta continuosly changes its weight, structure and
function during gestation. The placental barrier, the fundamental structure
for the feto-maternal exchange, is formed during the last quarter of
gestation showing a structural differentiation till birth. The aim of this
research was to analyse the placental parenchyma stereologically and
compare the size of surfaces engaged in the fetomaternal exchange during
the two periods of the 10th lunar month: from the 38th to the 39th week and
in the 40th week of gestation. It is stated that the surface density of the
trophoblast (P<0.025) and its specially differentiated areas alpha zones
(P<0.05) are significantly higher at the beginning of the 10th lunar month
than in the 40th week. The mean arithmetic thickness of the terminal
villous trophoblast increased from 4.75 micrometers at the beginning of the
10th lunar month to 5.95 micrometers in the 40th week (P<0.005). These
quantitative results demonstrate a possibly diminished gas diffusion in the
40th week as compared with the beginning of the 10th lunar month.
