I believe that most women can't help but think about their babies when they're pregnant, especially if they're pregnant.
Recently, Xiaomeng went to do four-dimensional color when an interesting thing happened, abdominal baby is really powerful, just to give a positive face, Xiaoli pointed to the mirror image surprised said: wow! The little one even opened her eyes? The doctor said, "I don't know if I'm looking at you, but I'm not sure if I'm looking at you!
The doctor explained with a smile: 2 months pregnant, the eyes of the fetus began to develop, to the fourth month of pregnancy, will be very sensitive to light, do four-dimensional open eyes, may be feeling the light on the probe, this is a normal phenomenon.
Some people have done tests: after 4 months of pregnancy, when the flashlight directly to the abdominal wall of the pregnant woman, the fetus will turn his face to the direction of the light, and in the light of the stimulation of the eyes open, but due to the strong light stimulation of the fetus vision is not good, do not recommend that pregnant mothers blindly try. The first thing you need to do is to get your eyes open, and then you'll be able to see the light, and then you'll be able to see the light.
In fact, there are many pregnant mothers who are as curious as Xiaomeng, and one of the most common questions I've heard is: How does the fetus breathe in amniotic fluid? Fetus in the amniotic fluid will not choke? Today, we will answer this question in detail.
Before the baby is born, his growth and development also need oxygen, just do not use the mouth to breathe, not with the lungs to breathe, the baby's lungs in the fetal period is solid, and all the oxygen it needs is through the placenta, the umbilical cord to realize, the placenta attached to the uterine wall, connected to the umbilical cord, the umbilical cord is connected to the baby, and between them to form a circulatory system.
When the mother inhales oxygen, it is passed to the fetus through the placenta and umbilical cord, and the carbon dioxide released by the fetus is passed back to the mother in reverse, and is subsequently expelled from the body.
Generally speaking, after 35 weeks of pregnancy, the fetal lungs can mature, of course, at this time still will not use it to breathe, the baby's first cry after birth, only to mark the official start of breathing with the lungs, and for this reason, they do not exist in the amniotic fluid drowning. If the baby is born prematurely earlier than 35 weeks of gestation, the lungs are not yet developed, and you need to resort to medical respiration and the use of relevant hormones to promote the maturation of the baby's lungs.
Why are fetuses able to breathe with their lungs at birth?
The fetus exercises its lungs by swallowing amniotic fluid in its mother's womb, stimulating the maturation and expansion of the alveoli in preparation for birth, and then the lungs really come into play when the baby cries out.
Mothers are curious about the 10 minutes after the birth of the baby was taken away to do? In fact, it is carried by the midwife to clean the respiratory tract, mouth and nasal cavity of mucus and amniotic fluid, to ensure that the respiratory system is functioning properly, and to provide the oxygen they need to avoid aspiration pneumonia.
Why is the fetus deprived of oxygen in the amniotic fluid?
The fetus in the amniotic fluid "breathing" and the mother is closely related, when there is a placental aging or oxygen delivery function is low, or the umbilical cord knots, torsion, around the neck and other circumstances, will lead to intrauterine oxygen deficiency, which will affect the fetal brain development, if not found in time, serious will also be The first thing you need to do is to get your hands on a new pair of shoes or boots.
1, crying
According to a report, scientists with 4D ultrasound imaging system technology to check the fetus, found that babies in the weeks before the birth of the baby will be crying, for this reason, pregnant mothers must maintain a good mood, or "mother and child", the baby will also follow the cry. The baby will be crying along with you.
2. Smile
Scientists in the use of 4D ultrasound, a rare capture of prenatal smile, which indicates that when the fetus is in a state of comfort, they will be comfortable, with a smile to express emotion, which must be the pregnant mother to do to make the baby happy things.
3, temper
Research has found that the fetus in the mother's stomach, the mother's emotional response to the changes is very sensitive, the mother to do "bad", "wrong", the baby is angry. But the baby will be angry, so pregnant mothers can control their own emotions, your every move, the baby can telepathic Oh!
