Question

Quizplus · Accepted Answer

The placental functions are carried out by the decidua basalis, which is a disc-shaped area located in the endometrium where the placenta attaches. The other choices, such as the trophoblast and allantois, are structures that participate in the development of the placenta but do not carry out its functions. The deciduas capsularis and parietalis are portions of the endometrium that do not directly contribute to the placenta.
