By which structure does the embryo developing in the uterus get nourishment?

The embryo developing in the uterus receives nourishment primarily through [C] the placenta. The placenta forms from the embryo’s tissues and the uterine lining and serves as a vital connection between the mother and the developing fetus. Through the placenta, the mother’s bloodstream delivers oxygen, nutrients, and antibodies to the fetus while removing waste products like carbon dioxide.
This exchange occurs through blood vessels in the placenta, allowing for the transfer of essential substances necessary for the embryo’s growth and development. Unlike the fallopian tube and uterus, which provide environments for early embryo development but do not directly nourish the embryo, the placenta acts as a specialized organ solely dedicated to facilitating the exchange of substances between the maternal and fetal circulations, ensuring the embryo’s proper nourishment throughout pregnancy.
