Placentanoun

(anatomy) A vascular organ in mammals, except monotremes and marsupials, present only in the female during gestation. 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.

Uterusnoun

(anatomy) The womb, an organ of the female reproductive system in which the young are conceived and develop until birth.

Placentanoun

(botany) In flowering plants, the part of the ovary where ovules develop; in non-flowering plants where the spores develop.

Uterusnoun

The organ of a female mammal in which the young are developed previous to birth; the womb.

Placentanoun

The vascular appendage which connects the fetus with the parent, and is cast off in parturition with the afterbirth.

Uterusnoun

A receptacle, or pouch, connected with the oviducts of many invertebrates in which the eggs are retained until they hatch or until the embryos develop more or less. See Illust. of Hermaphrodite in Append.

Placentanoun

(in flowers) part of the ovary wall to which the ovules are attached.

Placenta

The placenta is a temporary fetal organ that begins developing from the blastocyst shortly after implantation. It plays critical roles in facilitating nutrient, gas and waste exchange between the physically separate maternal and fetal circulations, and is an important endocrine organ producing hormones that regulate both maternal and fetal physiology during pregnancy.
