How to babies breathe in the womb? [facts you didn’t know]

We are writing this blog post because we wanted moms-to-be to know how babies breathe in the womb. Babies are not able to take their first breath until they are born, but they do make some kind of breathing motions while in the womb.

When a baby takes its first breath, it actually has to learn how to breathe on its own and will need time for that process. For now, though, let’s see what we can find out about babies’ breathing habits while still inside their momma.

Can i feel my baby breathing in the womb?

In the womb, babies do not breathe in the way we think of “breathing.” Babies depend on their mothers’ breathing to provide oxygen to their growing organs. This would allow for the baby to develop and lead to you being able to experience the movements of your baby in the womb if you put your palm on your tummy. The amniotic fluid is the fluid that surrounds your baby through the pregnancy and serves as a source of oxygen for the fetus.

How do babies breathe in the womb?

The placenta and umbilical cord are two organs that allow a growing newborn to get all of the nutrients it needs from its mother. This involves the presence of oxygen. The mother’s bloodstream receives oxygen with every breath she takes. The oxygenated blood is transported to the placenta and subsequently to the baby through the umbilical cord.

After nine months of development within a mother’s body, a baby exits the womb and experiences a complex physical transition. According to research, this transformation is one of the most complex things our bodies will ever perform. While newborns “practice” breathing in the womb, they don’t utilize their lungs before they take their first breath outside the womb.

Fetal breathing practice

The growing baby will begin to ingest small particles of amniotic fluid between weeks 10 and 11 of pregnancy. This “inhalation” is really more of a swallowing motion. It supports the development of the baby’s lungs. By the 32nd week of pregnancy, a baby will start practicing “breath-like” motions that include compression and expansion of the lungs rather than swallowing.

Even if the baby’s lungs aren’t completely grown at 32 weeks, a baby delivered at this point has a decent chance of surviving outside the womb.

The breathing exercise is a developmental milestone that ensures a successful first cry for the new newborn. At 36 weeks, the baby’s lungs are deemed developed. A newborn has received at least four weeks of breathing practice by that time.

Breathing during delivery

Your baby’s body is able to transition out of the womb and into the world anywhere around the 40-week period of pregnancy. The mother’s uterus contracts and retracts during childbirth. This leads her to have strong feelings that indicate the birth of the baby.

How do babies breathe in the womb after the water breaks?

The baby is squeezed by the contractions as it moves into position to exit the delivery canal. The contractions also force amniotic fluid out of the baby’s lungs, making it easier for them to breathe.

During the delivery process, the newborn may be exposed to oxygen. However, as long as the infant is attached to its mother through the placenta and the umbilical cord, it is not necessary for the newborn to attempt to breathe.

The infant will take a quick intake and breathe for the very first time on their own just a few seconds after delivery. For the first time, without the support of the mother, the lungs inflate and oxygen enters the baby’s bloodstream.

Breathing after birth

Your baby’s new lungs are most likely capable of carrying them throughout their lives. The respiratory system, on the other hand, is still growing. Alveoli are small air sacs in the lungs that allow our bodies to transfer oxygen. After birth, they will continue to grow and develop.

Most newborns have between 20 and 50 million alveoli in their lungs when they are born. By the time a youngster reaches the age of eight, he or she will have amassed up to 300 million. Alveoli fill the new surface area of the lungs as they expand. This allows the lungs to handle a developing human’s increasing oxygen requirements.

Our critical organs are encircled by the rib cage’s bones. These bones will get tougher as a baby develops, and the lungs will become more secure. This is a crucial stage in the development of the lungs.

Because of the fragility of our rib cages, we are very susceptible to “getting the wind knocked out of us” when we are initially born. In order to achieve an adult form, the ribs will also rise in the chest.

During birth, a newborn may inadvertently ingest or inhale pieces of the meconium, which is the first bowel movement. When this occurs, it’s critical to get the kid out of the womb as soon as possible and to get medical assistance. If the meconium isn’t eliminated, it might contaminate the baby’s lungs.

Do babies open their eyes in the womb?

Yes, of course! Babies open their eyes at 27-28 weeks of pregnancy. It can be observed during a 4D baby ultrasound when we can see newborns gazing about and moving their eyes. They are claimed to be able to perceive dark, light, and movement, but they are still unable to concentrate correctly.

The true colour is not picked up with 4D scans, so you won’t be able to see the colour of your baby’s eyes or hair. Because the skin, hair, and eye colour are related to parents’ genetics, one can guess what the baby will look like but there will always be surprises. In a 4D scan, the colour you see is produced by software that mimics certain skin colours.

How do babies get rid of waste in the womb?

The umbilical cord not only transports water, glucose, and nutrients to the growing fetus and feeds it with oxygen, but it also transports waste products such as urea, uric acid, and bilirubin to be discarded via the maternal blood circulation.

Your baby will take in nutrients and release waste while growing in the womb for several months. However, this waste is seldom in the form of feces.

When your infant poos for the first time, they produce meconium, which is a kind of waste. This normally occurs shortly after delivery, if not immediately. Meconium is tar-like feces that is dark greenish-black in colour. If you breastfeed, you’ll probably notice meconium for a few days after the baby is born.

This waste substance is produced in your baby’s intestines just before delivery. Nevertheless, difficulties may occur in certain situations, and your baby may create meconium while still in the womb. After that, the waste might gather in the amniotic fluid.

So, what happens to the waste?

Babies in the womb need aid in obtaining nutrition and eliminating waste. All of these functions are made possible by your placenta.

The placenta is composed of cells that develop throughout pregnancy. It connects to the umbilical cord, which is your baby’s lifeline since it is how you provide nourishment and oxygen to them.

Your baby will also release waste materials that you transmit out of your body via the placenta. So, throughout the whole nine months, there is no waste or urine floating around in your womb.

Final words

If you’ve been trying to figure out how a baby breathes in the womb, now you know. Your unborn baby will typically start taking his or her first breaths after birth as long as he or she is healthy enough to do so on their own. In some cases, like premature birth, doctors may give newborns oxygen through an incubator to help them breathe until they can do so on their own.

We hope these pregnancy tips help answer any questions you might have.
