Is the tube that carries blood, oxygen, and nutrients from the placenta to the developing child?

Umbilical vein transports blood rich in oxygen and nutrients from the placenta to the fetus. The unpaired umbilical vein is a vein present during fetal development and it transports the nutrient - and oxygen-rich blood from the placental villi via the umbilical cord to the embryo. The umbilical vein is connected to the two intraembryonic umbilical veins.
