It supplies food and oxygen from the mother to the foetus, and passes back waste. It is implanted in the wall of the uterus and links to the foetus through the umbilical cord. It is expelled after birth; Organ within the uterus that allows passage of substances between mother and fetus, such as food and oxygen; A structure that grows on the wall of the uterus during pregnancy through which the fetus is nourished; The part of a pistil or fruit to which the ovules or seeds are attached; {i} organ that forms on the wall of the uterus during pregnancy and carries nourishment to a growing fetus while removing waste products; that part of the ovary of a flowering plant where the ovules form; A membranous vascular organ that develops in female mammals during pregnancy, lining the uterine wall and partially enveloping the fetus, to which it is attached by the umbilical cord (source: dictionary com); The placenta is the mass of veins and tissue inside the womb of a pregnant woman or animal, which the unborn baby is attached to.

Organ in most mammals that develops in the uterus along with a fetus to mediate metabolic exchange. The umbilical cord attaches it to the fetus at the navel. Nutrients and oxygen in the mother's blood pass across the placenta to the fetus, and metabolic wastes and carbon dioxide from the fetus cross in the other direction; the two blood supplies do not mix. Other substances (e.g., alcohol or drugs) in the mother's blood can also cross the placenta, with effects including congenital disorders and drug addiction in the newborn (see fetal alcohol syndrome); some microorganisms can cross it to infect the fetus, but so do the mother's antibodies. The placenta, weighing a pound or more at the end of pregnancy, is expelled at parturition. Some animals eat it as a source of nutrients; in some species this stimulates lactation; the vascular organ that connects the fetus and the mother's uterus, through which metabolic exchange between the fetus and mother takes place; A temporary organ in the uterus that allows a fetus to receive nutrients, oxygen and other substances (such as medications) from the mother and to eliminate carbon dioxide and other wastes; The organ through which the foetus is nourished It also removes waste products; The vascular appendage which connects the fetus with the parent, and is cast off in parturition with the afterbirth; organ implanted within the uterus that supports an unborn child, which is attached by the umbilical cord; the vascular structure in the uterus of most mammals providing oxygen and nutrients for and transferring wastes from the developing fetus that part of the ovary of a flowering plant where the ovules form; The organ within the pregnant uterus through which the fetus derives its nourishment; at term it averages one-sixth the weight of the fetus; is is disk-shaped, about 2 5 cm thick, and 17 5 cm in diameter; A special tissue that joins the mother and baby It provides hormones and supplies the growing baby with water and nutrients from the mother's blood; A special tissue that joins the mother and fetus It provides hormones necessary for a successful pregnancy and supplies the fetus with water and nutrients (food) from the mother's blood; this organ grows in the uterus during pregnancy and connects the blood supplies of the mother and baby; special tissue that joins the mother and fetus to provide hormones necessary for a successful pregnancy, and supplies the fetus with water and nutrients (food) from the mother’s blood; A special tissue that joins the mother and fetus It provides hormones necessary for a successful pregnancy, and supplies the fetus with water and nutrients (food) from the mother's blood; the vascular structure in the uterus of most mammals providing oxygen and nutrients for and transferring wastes from the developing fetus; A structure that grows on the wall of the uterus during pregnancy, through which the fetus is nourished; The vascular organ lining the uterus which is produced during early pregnancy for the nourishment and protection of the developing fetus It is attached to the fetus by the umbilical cord, from which oxygen and nutrients flow between the fetus and the mother The placenta is expelled from the uterus after delivery of the baby; The special tissue that joins the mother to her fetus; it provides the fetus with oxygen, water, and nutrients (food) from the mother's blood and secretes the hormones necessary for successful pregnancy; n vascular organ, developed within the uterus of most mamals during gestation from the chorion of the embryo and a part of the maternal uterin wall; Sac which surrounds a fetus: supplies nourishment
