Picture of 34-week fetus in the belly

The most important way for the fetus to obtain nutritional energy in the uterus is not through eating, but through embryonic transport. The function of the placenta is to transport essential nutrients such as carbon dioxide, glucose, carbohydrates, vitamins, and nutrients in the pregnant mother to the fetus through active transport or facilitated diffusion, and to excrete carbon dioxide and other metabolic substances from the fetus. The natural fetus will have a swallowing posture from the 16th week in the womb, mainly swallowing the amniotic fluid and absorbing the water, glucose, carbohydrates, etc. in the amniotic fluid. This is the main way for the absorption of amniotic fluid. Therefore, the baby in the belly eats the amniotic fluid of the pregnant woman.

The fetus has weak inhalation in the uterine cavity, but the bronchi are not easy to open. After a pregnant woman gives birth, along with the baby's first cry, the bronchi expand and spontaneous breathing occurs. The fetus' trachea is opened, forming a normal breathing tract. Under B-ultrasound, the fetus's weak inhalation in the uterine cavity can be detected in the late pregnancy. Often combine fetal movement, amniotic fluid flow, fetal heart rate, and fetal movement to assess the fetal intrauterine reserve status. During pregnancy, you need to count the fetal movements yourself, have regular prenatal checkups, and actively eliminate pregnancy complications and complication, as well as fetal developmental deficiencies.

After 20 weeks of pregnancy, many pregnant women will feel that the fetus has hiccups in the uterine cavity, and this happens in waves. At present, in clinical work, it is believed that this type of hiccups are a kind of fetal movement, and does not mean that the fetus has abnormal conditions or lack of oxygen in the uterine cavity. However, when the fetus hiccups in the uterine cavity, you should also pay attention to the fetal movements, especially other forms of fetal movements.

If there is no obvious abnormality in the baby's fetal movement and hiccups, this situation will not affect the fetus at all. If there are only hiccups, and other fetal movements have subsided or the number of hiccups has also decreased, fetal heart rate monitoring should be done to assess the condition of the fetus in the uterine cavity.
