A 38-week-old baby is called a full-term baby. A 38-week-old fetus in the womb is usually about 50cm in length, with a biparietal diameter of about 9cm, a femur length of about 7cm, and a weight of 3,000~3,500g.
The circulatory system, respiratory, digestive system and other organs of the 38-week-old baby have developed and matured. The baby’s body is covered with a layer of fine downy hair and most of the white fetal fat is gradually falling off and disappearing, and the skin becomes smooth.
The chorionic villi and fetal fat and other secretions are swallowed by the fetus along with the amniotic fluid, stored in the intestines, and turned into black fetal stool, which is discharged within a day or two after the baby is born. The head of the fetus passes smoothly into the pelvic cavity of the pregnant woman and may be delivered at any time.
When the fetus is 38 weeks, pregnant women are advised to pay attention to the condition of the fetus at any time, and go to the hospital in time for pregnancy checkups to determine the condition of the fetus. Generally speaking, it is clearer through ultrasonography, and the pregnant women can clarify the specific condition of the child with the help of the doctor.
