Umbilical Cord, More Than a Lifeline to a Baby
The umbilical
cord, is also known as the navel string, or birth cord, is a conduit
between the developing embryo or foetus and the placenta. In human, during prenatal
development,
the umbilical cord is physiologically and genetically part of the foetus and
it’s normally contains two arteries which are the umbilical
arteries
and one vein, the umbilical vein, buried within Wharton's jelly. Although it's
not anatomically part of a human baby, but it plays a vital role in their
development and is much more than just a tube for transporting nutrition. Most
people think that the umbilical cord is a baby's life line, but there are so
many other amazing facts
about the umbilical cord that will make one think about it just a little
more.
What does an
umbilical cord do?
The umbilical
cord connects a baby’s stomach to the placenta which is in turn indirectly
connected to mother’s blood supply and measures around 20 inches long at birth.
The main function of it, is to provide nutrients and oxygen from the placenta
to the foetus and to return the blood without oxygen and waste products, like
carbon dioxide, from the baby back to the placenta. Towards the end of the
pregnancy, the umbilical cord also transfers antibodies from the mother’s
placenta to the foetus. This transfer of antibodies means that a baby has
immunity to infections for about three months after being born. The
umbilical cord sustains a foetus during their time in the womb, and then, in
most cases, is clamped and discarded without a thought. But, believe it or not,
it is much more than a lifeline and scientists are still discovering this
cord’s potential both in and out of the womb.
Does the umbilical
cord have a pulse?
The true fact is that
an umbilical cord cannot pulsate without the foetal heart pumping blood through
it. Actually a baby’s heartbeat makes the cord pulsate. But it is quite
possible that the pulsing umbilical cord is carrying little or no oxygen
because the placenta, which absorbs the oxygen, and may stop functioning almost
immediately after birth. The fact that stands from it, is that the cord is
pulsating tells us nothing about whether a baby is receiving any oxygen.
Structure of this
cord
The umbilical cord is
made up of -
·
Two
arteries which return the waste products
·
One
vein that is usually larger than the two arteries and provides the nutrients
and oxygen
·
A
sticky gelatinous substance that envelops the arteries and vein, known as
Wharton’s jelly
·
A
membrane called the amnion that covers that Wharton’s jelly
Most people think
that the umbilical cord is, a slippery looking cord that connects a baby to the
placenta during pregnancy. And moreover, this cord has pulse. But from
aforesaid fact, one get to understand this cord’s vital and it is not actually
have any pulsate. Though umbilical pulse is true in turn of
the fact that because of baby’s heartbeat make it to do so, not from its very
own.
