Question

Making of Umbilical Cord
Umbilical cord is made up of?

Answer 1

The umbilical cord is made up of:

one vein that carries blood rich in oxygen and nutrients from you to your babytwo arteries that return deoxygenated blood and waste products, such as carbon dioxide, from your baby back to the placenta

These blood vessels are enclosed and protected by a sticky substance called Wharton's jelly, which itself is covered by a layer of membrane called the amnion.

Towards the end of your pregnancy, the placenta passes antibodies through the umbilical cord from you to your baby. These give your baby immunity from infections for about three months after birth. However, it only passes on antibodies that you already have.
