The uterine lining is thickened every month support the growing embryo. Followed by fertilization, placenta is developed which serve to provide nutrition and oxygen to developing embryo from the mother's blood. It is a disc embedded in the uterine wall and contains villi on the embryo's side of the tissue while blood spaces surrounding the villi are present on mother’s side. Waste products of developing embryo are removed by transferring them into the mother's blood through the placenta.
