Belly Button Science 101 #sciencematters

I can’t help but chuckle at the “science matters” rhetoric lately….good grief!

I woke up thinking about our belly button!!! Yes, of all things….our belly button! Everyone has one!
I know it’s silly…but if you really think about it. Pause for a moment….what is our belly button
?
It is truly an amazing thing….it is evidence of the mother/child connection (scientific evidence once again proving the mother/child bond). Our Belly Button is evidence of the incredible connection through the umbilical cord.
The Umbilical Cord and the Placenta in the womb are the connecting points. The Placenta is where the baby’s blood picks up oxygen and nutrients from the mother‘s circulatory system.
Inside the umbilical cord are three vessels: two arteries and one vein. The vein carries oxygen and nutrient-rich blood from the mother, through the placenta, back to the baby’s liver. There, vessels branch out to help oxygenated blood reach the baby’s 4 chambers in it’s heart. And extra opening, the foramen oval, allows the blood to flow from the left to the right atria, or upper chambers. Only a little blood leaves the right atrium to go to the lungs, thanks to the presence of a tiny shunt, called the ductus arteriosis, which directs blood away from the pulmonary artery into the aorta, where it can better serve the baby’s brain and other parts of the body.
So, back to the belly button
….at delivery, when the baby is born and takes its first breath, the foramen oval and the ductus arteriosis close up and disappear, so that higher blood pressure flows to the lungs to pick up vital oxygen. Circulation to the placenta then ceases – the arteries close first to prevent blood leaving the baby’s body. The umbilical vein continues to provide oxygenated blood to the newborn for an average of 15 minutes (unless it is clamped and cut sooner – perhaps theirs an advantage to both mother and child to not “clamp” so quickly?) The umbilical cord will pulse until the process is complete.
So, then, the umbilical cord stump, also known as the BELLY BUTTON, will dry up and fall away; it leaves a scar. Within a week of the baby’s birth, the umbilical vein inside the body becomes fibrous. It becomes the round ligament of the liver, which extends from the umbilicus to the transverse fissure, where it joins another ligament. Together they support and separate the liver lobes.
The BELLY BUTTON
is our lifelong reminder of our connection to our birth mother.
And THAT my friends is BELLY BUTTON Science 101.
