Solution
The placenta develops from two sources: trophoblastic tissue derived from the embryonic blastocyst and maternal endometrial tissue of the uterus. This dual origin allows the placenta to serve as an effective interface between maternal and fetal circulations while maintaining separation of maternal and fetal blood.
