The _______ is the Organ of Exchange Between the Mother

Question

The _______ is the organ of exchange between the mother and the embryo.
A) amnion
B) cervix
C) corpus luteum
D) placenta

Accepted Answer

The placenta is the organ of exchange between the mother and the developing embryo. It is formed from the tissues of both the embryo and the mother and is responsible for transferring oxygen, nutrients, and other essential substances from the mother's blood to the fetus, as well as removing waste products from the fetal blood. The other options (amnion, cervix, corpus luteum) are not directly involved in the exchange of materials between the mother and embryo/fetus.
