<h3>What is umbilical cord?</h3>
- During pregnancy, a tube called the umbilical cord joins you to your unborn child.
- It has three blood vessels: two arteries transfer waste from your baby back to the placenta and one vein carries food and oxygen from the placenta to your baby.
- Because it transports the baby's blood back and forth between the newborn and the placenta, the cord is sometimes referred to as the "supply line" for the infant.
- It provides the newborn with nourishment, oxygen, and waste product removal.
- The umbilical cord begins to grow five weeks after conception.
- Wharton's jelly, a gelatinous substance primarily formed of mucopolysaccharides that shields the blood vessels inside the umbilical cord, is present there.
