The prime functions of the umbilical cord (also called as navel-string or birth cord) are it connects your baby to the placenta to provide the required nutrients for nourishment.

It contains three vessels: one vein, which carries blood from placenta to the baby and two arteries, which carry back blood from the baby to the placenta.

The blood in the arteries contains waste products produces due to the baby’s metabolism and Carbon dioxide. Carbon dioxide is transferred through the placenta to your lungs via the bloodstream, where it’s breathed out.

Transportation of Oxygen from red blood cells (RBC) in your circulation, across the placenta to the baby in the umbilical vein is also a key function of the umbilical cord.

Besides oxygen, the umbilical vein also transports the required nutrients from the placenta to your baby.

The umbilical cord is coiled like a spring during the ninth week and usually in the clockwise direction so that the baby is free to move around.

The baby’s movements are itself to encourage the umbilical cord to the coil. The cord is usually 1 – 2 cm in diameter and 60 cm in length, which is more than sufficient for hassle-free delivery.

After delivery, the cord close by themselves. There are no nerves present in the cord, so cutting the cord after delivery is a painless procedure for your baby.
