I believe most people know that when giving birth, the fetus's head basically points down first because the fetus's breathing needs to be ensured. Everyone is curious about the changes in the uterus. In fact, the editor has done some research on this aspect. Many people are more concerned about how many months of pregnancy the fetus's head will point down. The editor can explain it. Eight months fetus At this stage, the fetus is 32 cm long (from head to hips) and weighs 2.5 kg. It has fully developed, with the head in proportion to the rest of the body. More fat has accumulated under the skin to prepare for maintaining body temperature after birth, but the skin is still relatively thin. Face: The skin on the fetus's face is much smoother and has fewer wrinkles. During the ultrasound examination, the fetus's face could be clearly seen, the fetus blinked more often, and light could be felt through the abdominal wall. If the fetus were born now, it would blink automatically. Upper and lower limbs: They are well developed, muscles and nerves are connected, and more coordinated movements are formed. After the fetus gets used to gathering its limbs and lying in the uterus, it can grab things. Skin and hair: As fat accumulates, the skin becomes less transparent. As the blood vessels become less visible, the skin turns pink. The fetal sebum increases and hair appears on the head. Lungs: The lungs are still developing. If the fetus were born now, with artificial respiration, it would have a great chance of survival. Brain and nervous system: They are fully developed. If the fetus is born now, he will already have many reflexes, such as sucking reflex, but his coordination ability is poor. Digestive system: Meconium fills the intestines. It is dark green and thick, and contains dead cells and secretions from the intestines and liver. During labor, the fetus is stimulated to pass meconium. As the placenta matures, nutrient exchange is optimized. Now he can distinguish between light and dark. Because there is no extra space in the uterus, the fetus has turned into a head-down position at this time, ready for delivery. During pregnancy, you should always pay attention to the development of the baby, because he is still relatively fragile. The embryo is also gradually developing after continuous improvement in the uterus. When observing fetal movements, once you find that the fetal head begins to move downward, it may be that the birth is about to begin, mainly to make it easier for the baby's head to come out first, thus avoiding breathing difficulties. |
