 Everyone
in the world has a belly button. It is located
on your stomach. However, it does
not get much attention. Although it is very small and barely noticeable,
your belly button is a part of your body. This week, let’s learn some
interesting facts about your navel!
All placental mammals have navels,
but generally, navels are more
clearly seen in humans than
other mammals. A navel is a closed hole that forms when the umbilical cord is cut from
a newborn baby. Your belly
button marks the spot where your umbilical
cord was once attached.
 As
a baby develops inside the mother, he or
she floats in a fluid inside the mother’s
womb. The baby cannot breathe air or eat food while
he or she is in there. The baby needs the umbilical cord to survive. It is a flexible tube that carries oxygen and nutrients from the mother
to the baby. The umbilical cord also carries wastes away from the baby
back to the mother so she can get rid of them.
When the baby is born, he or she doesn’t need an umbilical cord anymore.
This is because they can breathe on their own.
They can also drink milk and get rid of wastes on their own. A doctor
cuts the umbilical cord and a tiny stump is left. After a few
weeks, the stump falls off and the baby has his or her own belly button.
According to researchers at the University
of Missouri in the U.S., a perfect belly button is small
and shaped like the letter T.
Unlike other body parts,
your belly button needs very little care. You don’t need to clean
it out every day. Just taking regular baths or showers
should be enough to keep your belly
button clean and healthy. |
