Next, the editor will explain these aspects in detail for everyone, hoping to be of some help to everyone. Please listen to the editor's detailed introduction.

4 weeks: The fetus is only 0.2 cm. At this time, the sperm and egg have just combined to form the embryo, the amniotic cavity has just been formed, the volume is small, and no signs of pregnancy can be seen on ultrasound.

5 weeks: The fetus is 0.4 cm. At this time, the embryo enters the test tube stage, the amniotic cavity expands, and initial cardiovascular and cerebrovascular diseases appear. B-ultrasound can show a small fetal sac.

6 weeks: The fetus is 0.85 cm, the head, brain alveoli, frontal organs, respiratory, digestive, nerve and other organs are separated, the gestational sac can be seen by B-ultrasound, and the fetal heart rate and fetal heartbeat can be seen.

7 weeks: The fetus is 1.33 cm. The embryo has already taken on the human prototype. The body segments have all been divided, the limbs have been separated, and the various organs are further developed.

8 weeks: The fetus is 1.66 cm. The fetal shape is stable. The head, body and limbs of the fetus can be separated, and the head of the fetus is larger than the body.

9 weeks: The fetus is 2.15 cm, the head is higher than the body trunk, the various positions are more obvious, the head begins to thicken, and the embryo begins to grow. 10 weeks: The fetus is 2.83 cm, the fetus's internal organs have already formed, and the embryonic prototype has been formed.

11 weeks: The fetus is 3.62 cm, the internal organs are further developing, the embryo is growing, and the B-ultrasound shows that the gestational sac has completely disappeared and the embryo is clearly visible.

12 weeks: The fetus is 4.58 cm, the reproductive organs are basically grown and developed, the skull height is clear, the biparietal diameter can be measured, and significant deformities can be diagnosed. From then on, the internal organs tend to be healthy.

The above is some of the content about the standard list of fetal abdominal circumference that the editor has introduced to everyone. I hope it will be of some help to everyone.
