Baby

The first ultrasound examination is important in the determination of the settlement of the pregnancy and the number of babies. Is it a single baby or do you have twins? Is its intrauterine settlement normal? Is its heart beat normal? Early ultrasound is important in answering all these questions. The height of the embryo exceeds 1 mm. Irregular beats have started in a tube-like structure that will form the heart in the future. The baby starts to feed from the mother via the placenta and the umbilical cord. Chambers of the heart start to form starting with the 6th week in the developing embryo and heart beat becomes regular. During this period, while the structure that will form the spinal cord starts to close upon itself, head-neck, nervous system, lungs, liver and kidneys start to develop.
