While in the womb, the fetus never uses its lungs to breathe. But after giving birth Instead, she took her first breath almost as soon as she was born.
How did this miraculous change happen? “We’ve all made these incredible changes,” says David Tingay, a neonatologist at the Royal Children’s Hospital in Melbourne. Australia said “This is one of the most basic things we have to do.”
But how does a baby breathe without lungs in its mother’s womb? It may be hard to believe, but fish and humans look strikingly similar four weeks after conception.
At first glance, both embryos are so similar they can hardly be separated. But as time passed Fish replace folded neck structures with fibrous tissue called gills, but in humans, these same structures become our jaws.
After 4 or 5 weeks, our respiratory system begins to develop into lungs. By the end of the 8th week, the entire basic structure of the lungs is formed. Lung tissue begins to grow and mature and is ready to breathe in and breathe out in the 9th month.
But during the time of pregnancy The baby’s lungs are unable to breathe. It is filled with fluid, which is secreted by the lungs themselves to cushion and protect the developing organ from compression or damage.
Therefore, the baby’s breathing is a function of “vascular network” instead, in other words When in the womb We breathe through liquids.
These networks facilitate the delivery of oxygen, nutrients and waste disposal. Everything goes in and out through the mother’s bloodstream. Scientists call this ‘The process of placental respiration’
Oxygen-rich blood is distributed to the developing organs and tissues towards the end of pregnancy. The baby is ready to breathe on his own.
“Giving birth is probably the only time you want your child to cry out loud,” says Caraciolo Fernandes of Baylor University School of Medicine. and Texas Children’s Hospital said “You want them to cry as much as possible. Because it really helps open up the lungs.”
As the baby travels through the birth canal Compression squeezes some of the fluid out of the lungs. Pressure and hormonal changes also stimulate the body to absorb fluid.
and when they are born Everything within seconds after birth will signal the baby to take its first breath.
“Fetal lungs act like a big sponge that suddenly fills with air space,” Tingay said. “That’s what a baby does on its first breath.”
When the first air flows in It pushes out any remaining fluid in the lungs. Helps open the lungs to work fully. Liquid is expelled from coughing. or absorbed by the bloodstream and lymphatic system
These procedures have led doctors and scientists to discourage mothers from choosing a C-section. Because it is a method that does not occur naturally.
To encourage the baby to breathe
Some people may have fluid remaining in their lungs, causing problems after birth. Including a premature cesarean section may cause the lungs to not fully develop. unless the doctor gives permission
All of the natural pathways that occur in the womb allow the baby time to form, develop, train and prepare their muscles, tissues, nervous system and gut system. For the most important moment: changing breathing with the placenta to breathing with one’s own lungs.
We cannot know for sure how the mermaids in stories were able to breathe underwater. But now we know quite a lot about that. The baby resembles a mermaid in some ways.
Ariel has traded her voice for life on land. Likewise, a baby has been freed with its first breath to live on earth.
