Did You Know Where The Signal That Starts The Delivery Is Coming From? From The Lungs Of The Baby!

Some babies are born accurately at week 38, others well in advance and in some cases the baby is born at 42 weeks. As we know, although there is an estimate of the duration of pregnancy in humans, in nature there is no straight line . Each cycle in man and nature in general, is changing. How does the baby know that he is ready to be born? Where does the impulse that gives birth originate?

Numerous cesareans are currently scheduled for each day. Therefore, it is easy to know when our baby will be born. However, mothers who are going to give birth in a natural way , live full of uncertainty . In the 37th week, we hope that at any moment the birth will occur.

Many think that the symptoms that the mother experiences that announce the birth, are born in her. However, it has been discovered that it is actually the baby who activates it. According to research, the sign that activates labor comes from the baby’s lungs . We tell you how it happens.

The home button is in the lungs of the baby

Have you noticed that to determine that the baby is ready to be born, experts are concerned about lung maturation ? Well apparently the reason is very specific. In the baby’s lungs is the button that starts labor.

Specialists at the Southwestern Medical Center at the University of Texas in the United States have made this finding. According to their interpretation of the results, babies are not born until they are prepared to do so . When does an apple fall? When it is ripe.

In such a case, a baby can not come into the world if he is not qualified to survive on the outside . As you can imagine, you can not live if you can not breathe. The organs of the body need to be ripe to be able to stay outside, but the most important thing is breathing.

People can fail other systems and survive like this. However, when the respiratory system fails, we enter into crisis and we can die in a short time. This is why the baby needs his lungs to be ripe to be born.

According to research, the lungs are considered to be mature when their lung surfactant levels are complete . The known surfactant is an element present in all humans within the alveoli, its function is to make breathing possible. This substance prevents the alveoli from becoming totally devoid of air when they empty when breathing.

How and when does it happen?

Research on mice found that there is a pair of proteins capable of controlling the activation of the genes present in the surfactant. These proteins known as SRC-1 and SRC-2, do not activate until the entire period of gestation has elapsed . Until the cycle is completed, the process for the surfactant is completed.

Once the lungs mature, they perform the signal that gives birth . Just like when you fill a bucket of water , you start filling up when you need it and you close the key as long as it is complete what you expect. Experiments revealed that by suppressing the action of the proteins towards the surfactant, deliveries were delayed in a period equivalent to 4 weeks in human pregnancy.

For the last days of gestation, the SRC-1 and SRC-2 proteins increase the secretion of surfactant . Since not all pregnancies are the same and the human body is changing, it does not happen at the same time. Each organism is different, so birth times are relative.

It is believed that also increases the amount of platelets, necessary to defend the body on the outside. All the increase of these substances, can be perceived in the increase of these in the amniotic liquid .

Researchers say that in the uterus there is a sensitivity to the increase of these substances, which is why a response is generated . That is, the baby’s lungs are filled with surfactant, consequently increasing the amount of this in the amniotic fluid. In response, the mother’s uterus swells and goes into labor.
