‘The umbilical cord is very important because it is the baby’s lifeline. It brings everything that the baby needs to grow and be healthy from the mother. And then the baby sends back the used, the used carbon dioxide. His waste products to mom and to that umbilical cord and her body disposes of them. It has a very interesting shape and composition  because it’s made out of this Wharton’s jelly, which is full of mesenchymal STEM cells. And the Wharton’s jelly helps to protect the blood vessels in the umbilical cord from getting shut off or inter the flow interrupted, because it makes the cord very full and round. And so the baby can’t squeeze it. And it’s very unlikely that the baby will push up. The fetus will push up against it and the uterus, that kind of thing. So it protects it.’

‘The Wharton’s jelly protects it from being shut off. And as a baby comes down the birth canal, the cord continues this function of exchanging the nutrients and this function continues for a while after the baby’s born. So the baby continues to get oxygen for at least a couple of minutes after he’s born through the cord. if we leave the cord attached to the placenta and the baby until the placenta is ready to deliver, then the baby gets all of his blood from the placenta that he needs. The umbilical cord is really the baby’s lifeline. And it’s very interesting because you see in women who eat very well and take care of themselves and are healthy, that the umbilical cord is usually nice and full at birth. And then sometimes when there’s been problems or issues, the cord is very thin and not as protective of the infants. Anyway, it plays an extremely important role It is the babies, It is the fetuses lifeline during the pregnancy.’
