What happens to umbilical cord after delivery?

In the womb, the umbilical cord delivers the oxygen and nutrients needed to allow your baby to grow. After birth, the cord is clamped and cut, leaving a stump. This eventually falls off, healing to form the umbilicus (belly button). There are ways for you to prevent problems during healing.

Breathing: It is the job of the umbilical cord to transport oxygen-rich blood to the fetus. Excretion: The carbon dioxide released by breathing as well as waste from nourishment are expelled through the umbilical cord. High stem cell content.

What are the components of an umbilical cord?

THE UMBILICAL CORD brings together, in the same mesenchymal core, the components of the connecting stalk (the allantois and umbilical vessels) and the vitelline duct and vessels .
