The fetal membranes surround the developing embryo and form the fetal-maternal interface. The fetal membranes are derived from the trophoblast layer (outer layer of cells) of the implanting blastocyst. The trophoblast layer differentiates into amnion and the chorion, which then comprise the fetal membranes. The amnion is the innermost layer and, therefore, contacts the amniotic fluid, the fetus and the umbilical cord. The internal pressure of the amniotic fluid causes the amnion to … WebFunctions of the Allantoic Membrane The allantoic membrane acquires an extensive blood supply from caudal branches of the aorta that break up into an extensive vascular network. The allantois and chorion fuse early in gestation so that the vascular system of the allantoic membrane supplies the entire chorioallantoic placenta.
