Placentation refers to the formation, type and structure, or arrangement of placentas. The placentation begins once the embryo begins to implant into the wall of the uterus, involves the remodeling of blood vessels in order to supply the needed amount of blood and is delivered with the fetus at birth. The placenta will have both a fetal and a maternal component. The developing fetus is connected to it via an umbilical cord. The placentation can provide nutrition, gas exchange, fetal waste products removal and immune support for growing fetus.
