SummaryBecause the placenta functionally represents a rather intimate association of the fetal capillary bed to maternal blood, its gross anatomy primarily concerns vascular relations. The fetal surface of the placenta is covered by the transparent amnion beneath which the fetal chorionic vessels course. A section through the placenta in situ includes amnion, chorion, chorionic villi and intervillous spaces, decidual plate, and myometrium. The maternal surface of the placenta is divided into irregular lobes by furrows produced by septa, which consist of fibrous tissue with sparse vessels confined mainly to their bases. The broad-based septa ordinarily do not reach the chorionic plate, thus providing only incomplete partitions.
