Compare with Definitions

Chorion

The chorion is the outermost fetal membrane around the embryo in mammals, birds and reptiles (amniotes). It develops from an outer fold on the surface of the yolk sac, which lies outside the zona pellucida (in mammals), known as the vitelline membrane in other animals.

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.

Chorion

The outer membrane enclosing the embryo in reptiles, birds, and mammals. In placental mammals it contributes to the development of the placenta.
Sep 27, 2021

Placenta

A flattened circular organ in the uterus of pregnant eutherian mammals, nourishing and maintaining the fetus through the umbilical cord.

Chorion

The protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus.

Placenta

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

Chorion

The outer case of an insect egg.

Placenta

A membranous vascular organ that develops in female eutherian mammals during pregnancy, lining the uterine wall and partially enveloping the fetus, to which it is attached by the umbilical cord. Following birth, the placenta is expelled.

Chorion

(botany) The outer membrane of seeds of plants.
Sep 27, 2021

Placenta

A similar organ in marsupial mammals, consisting of a yolk sac attached to the uterine wall.
Sep 27, 2021

Chorion

The outer membrane which invests the fetus in the womb; also, the similar membrane investing many ova at certain stages of development.

Placenta

An organ with similar functions in some nonmammalian animals, such as certain sharks and reptiles.

Chorion

The outer membrane of seeds of plants.

Placenta

(Botany) The part within the ovary of a flowering plant to which the ovules are attached.

Chorion

Outermost membranous sac enclosing the embryo in higher vertebrates (reptiles, birds and mammals)
Sep 27, 2021

Placenta

(anatomy) An organ in most mammals during gestation that supplies food and oxygen to the foetus and passes back waste. It is on wall of the uterus and links to the foetus through the umbilical cord. It is expelled after birth.
Sep 27, 2021

Placenta

(botany) In flowering plants, the part of the ovary where ovules develop; in non-flowering plants where the spores develop.
Sep 27, 2021

Placenta

The vascular appendage which connects the fetus with the parent, and is cast off in parturition with the afterbirth.
Sep 27, 2021

Placenta

The part of a pistil or fruit to which the ovules or seeds are attached.
Sep 27, 2021

Placenta

That part of the ovary of a flowering plant where the ovules form
