Schematic drawing of the placenta (cross-sectional image). The chorionic plate (fetal side) is a mass of connective tissue that contains the amnion, main stem villi, and chorionic arteries and veins. The basal plate (maternal side) consists of trophoblastic and decidual cells; it contains the placental septa, decidua basalis, and endometrial arteries and veins. The chorionic and basal plates are separated by the intervillous space; exchange between fetal and maternal circulatory systems occurs between the main stem villi and the maternal endometrial vessels in this space
