Structurally the placenta has two components, the fetal chorion frondosum and the maternal decidua basalis; functionally, the placental circulation involves two distinct parts, the fetal blood vessels in the chorionic villi and the maternal blood in the intervillous spaces. We are your community theater. ; The placenta has two components: the fetal part (chorion frondosum) and the maternal part (decidua basalis). The placenta is thus a dual structure composed of the decidua basalis or maternal placenta and the chorion frondosum or foetal placenta. The chorion frondosum produces millions of villi that carry fetal capillaries so that the blood within them can come into close contact with maternal blood flowing through the intervillous spaces. : the part of the chorion that has persistent villi and that with the decidua basalis forms the placenta see chorionic villus sampling.
