How does newborn cry meeting blush to return a responsibility

First: the fetus does not breathe in the womb. After birth, the baby must rely on its own breathing to inhale oxygen and emit carbon dioxide. There is no air in the lungs of the fetus. The lungs are still a solid mass of tissue. After the baby was born, because the body was no longer curled up, the original curled chest suddenly expanded, the chest immediately expanded, and the lung lobes also opened. At this time, the first breath of air was inhaled. When air enters the alveoli from the trachea, the inspiratory muscles relax immediately, the expiratory muscles contract immediately, and the thorax contracts to its original size, forcing the air out of the lungs. When the exhaled gas passes through the larynx, the larynx muscles contract, the two vocal cords in the larynx cavity are tightened and close together, the gas impacts the vocal cords, and the vocal cords vibrate and emit a cry like cry. When the baby was born, the amount of carbon dioxide in the blood was more, which stimulated and excited the respiratory center, so they all took a big breath. Therefore, every baby will cry for a while after birth. When the normal rhythm of respiratory activity is established, it will not cry any more.

Second, we know that the fetus in the mother's abdomen is attached to the mother through the umbilical cord and placenta to obtain nutrition. In the 9-month life in the womb, the fetus is not worried about food and clothing. Instead, it relies on the mother to transport oxygen and nutrients to them through the placenta and umbilical cord to get everything they need for growth. Even a few seconds before birth, the fetus still lives on the oxygen provided by the umbilical cord. That is to say, the fetal lung function is completely performed by the mother through the placenta, and it does not need to work.

Third, it has been proved that he can handle the problem well. As soon as he was born, under the stimulation of the cold air around him, his small nose and mouth would open and immediately start breathing, allowing the outside air to flow into his lungs. The blood then flows from the heart into its pulmonary vessels, seeking the oxygen it has just inhaled. So far, the baby has successfully completed the lung breathing, blood circulation also into the normal way. In just a few minutes, the blood circulation through the umbilical cord was terminated, and the little life was completely independent.
