The decidua basalis is the name for the maternal portion of the placenta. Oxygen and nutrients from the maternal blood permeate through the villi's walls and into the fetal capillaries in the inter-villous gaps.
<h3>What is Placental membrane ?</h3>
Blood from the mother and the fetus are separated by the placental membrane. The chorion is the name for the fetal portion of the placenta. The decidua basalis is the name for the maternal portion of the placenta.
At eight days after ovulation, the blastocyst is fully entrenched in the endometrial stroma in humans. Fibrin covers the entry point, and endometrial epithelial cells develop on top of it to further embed the blastocyst in the endometrium (Bischof and Campana 1996).
The uterus houses the placenta, a transient pregnancy organ. It is made up of elements from the mother and fetus. The chorion frondosum creates the fetal portion, and the decidua basalis creates the maternal portion.
