Embryo pronunciation

How is embryo pronounced? Test tube embryo production pinyin letter vaccine: pēitāi, production description vaccine: (1) The animal body that grows and develops in the early stage of pregnancy, which is formed by the growth and development of the egg after fertilization. The human test tube embryo is connected to the embryo through the fetal umbilical cord, and absorbs nutrients from the pregnant mother through the embryo. (2) Specifically refers to the embryonic stage of something.

1. What is each process of embryonic development like?

1. The sperm and egg combine and undergo several divisions to form a cell mass, which gradually grows and begins to divide at the same time. Part of it becomes the fetus, and the other part becomes attached organs that provide nutrition and protection to the fetus. It is the first week of life.

2. In the third week, the baby grows and develops very rapidly. The spine is formed, and the brain, spinal cord, central nervous system and eyes all have a certain prototype. At the other end of the spine is a small tail. At this time, blood vessels begin to appear, and the heart has not yet formed, but there is heartbeat at the position where the heart is transformed.

3. In the 6th week, the embryo develops rapidly, the heart begins to divide the atria, beats regularly, and begins blood supply. The fetus's body cells are still rapidly disintegrating. The prototypes of the kidneys and heart have already developed, and the neural tube has begun to connect to the brain and spinal cord.

5. In the 40th week, most babies will be born in this week. Only about 5% of babies can be born exactly on the due date. It is normal to be born two weeks early or two weeks late. At this time, the amniotic fluid of the fetus begins to become turbid and milky white from the original clear and transparent due to the shedding of human surface hair and vernix caseosa and the formation of other secretions. The function of the placenta then gradually declines until the baby is delivered.

2. What are the common problems in baby development?

1. When checking the fetal heart rate with a monitor before delivery, only if an abnormality is found, usually due to a long delay in changing gears, will you consider whether the baby has the umbilical cord around the neck. If diagnosed, the pregnant woman will need a caesarean section. Pregnant mothers do not need to worry too much. This situation does not mean that a caesarean section is necessary. The final choice of delivery method needs to be decided after a comprehensive evaluation.

2. Only in very rare cases will the umbilical cord be tightly wrapped around the fetus' neck. In most cases, the degree of entanglement is relatively light. And if the umbilical cord entanglement makes the fetus feel uncomfortable, they will take certain effective measures to rotate up and down to find a comfortable position around, thereby solving the umbilical cord entanglement. But if you circle it a few times, the fetus is more likely to come out on its own.

3. With the development of medicine, the chance of fetal death due to umbilical cord around the neck is getting smaller and smaller. The delivery process will not be delayed due to the umbilical cord around the neck, and the umbilical cord around the neck is not the only reason for the death of the fetus in the womb. Pregnant women should have confidence in their doctors and maintain a calm mental state.

The growth and development of test tube embryos is very important for every mother, and there are many things that need to be paid attention to in daily life. If anything affects the growth and development of the baby, it will cause great health damage to the baby's future. I also need to have a deep understanding of each process of embryonic development, and I believe that this will have a great effect on the healthy growth of the baby.
