Question

Quizplus · Accepted Answer

The placenta is an organ that forms during pregnancy to provide oxygen and nutrients to the developing embryo or fetus. It also acts as a barrier, preventing the mother's blood from mixing with the blood of the developing embryo or fetus. It is fully developed by the end of the first trimester (approximately 12 weeks) of pregnancy, not six months after birth. It is not the same as the fluid-filled sac that houses the developing embryo or fetus, which is called the amniotic sac.
