conduit between embryo/fetus and the placenta
The umbilical cord is the tube-like structure that connects a developing baby to the placenta during pregnancy. It carries nutrients and oxygen from the mother to the fetus and removes waste products, making it essential for the baby's growth and survival before birth.

Encyclopedic overview
In placental mammals, the umbilical cord (also called the navel string, birth cord or funiculus umbilicalis) is a conduit between the developing embryo or fetus and the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried within Wharton's jelly. The umbilical vein supplies the fetus with oxygenated, nutrient-rich blood from the placenta. Conversely, the fetal heart pumps low-oxygen, nutrient-depleted blood through the umbilical arteries back to the placenta.
