Expectant mothers enjoy the time when their babies are in their tummies and feel them growing day by day. Let’s learn more about fetal babies in these wonderful years. Pregnancy is the process of the baby’s development and growth in the mother’s body, beginning with the fertilization of a mature egg and ending with the expulsion of the fetus and its appendages from the mother’s body, the whole process – 38 weeks (266 days). We usually count from the first day of the last menstrual period for pregnant mothers with regular menstrual cycles for ease of calculation, that is, a total of 40 weeks. In case of abnormal menstruation, the week of pregnancy is based on the physician’s verification! There are a total of 3 stages of pregnancy: I. Before 14 weeks (Early Pregnancy) Early pregnancy is a critical time for the formation of the baby’s major systems and organs. Our initial labor and delivery checkup is also at this stage. 8 Weekend: the embryo takes on its first human form, and the heart tube beats are seen on B-mode ultrasound. Exposure to toxic and harmful substances or consumption of certain medications throughout the early pregnancy stage may directly lead to miscarriage and fetal malformation. Second, 14 weeks to 27 + 6 weeks (mid-pregnancy) Fetal baby fully formed and began to grow, 16 weekend or even earlier B ultrasound has been able to confirm the sex of the baby, some pregnant mothers can even feel the fetal movement. This stage of obstetric examination can screen the fetal baby for the presence of major lethal malformations. Third, more than 28 weeks (late pregnancy) At the end of the 28th week, the average length of the baby is 35cm and the weight is 1100g. from 28 weeks onwards, babies that have to be born early for some special reasons already belong to the vital little life! A baby born after 37 weeks is called a full-term baby. If the gestational week reaches 42 weeks it is an expired pregnancy, which is very dangerous for the baby. After talking about the general growth and development of the baby, it is also important to understand the baby’s various “equipment” in the pregnant mother’s stomach! Fetal baby equipment: placenta Functions: gas exchange (exhaust, oxygen); nutrient supply; diarrhea fetal metabolites; defense function (against germs); synthesis of hormones and enzymes. Fetal equipment: fetal membrane two layers: chorionic villus and amniotic membrane composition Function: in the labor initiation has a certain role Fetal equipment: umbilical cord connecting the fetus and the placenta cord-like tissue, the embryo and fetus with the help of the umbilical cord suspended in amniotic fluid, umbilical cord section in the center of the umbilical cord has an umbilical vein on both sides of the two umbilical arteries, the umbilical cord pressure can be caused by fetal distress or even endangered the life of the fetus. Fetal equipment: amniotic fluid is filled with liquid in the amniotic cavity Role 1: protect the fetus baby let the baby not squeeze, prevent fetal deformities, fetal limb adhesion; to maintain a constant temperature in the amniotic cavity; contractions, amniotic fluid can make the pressure evenly distributed. Role 2: Protecting pregnant mothers Reducing the discomfort of fetal movement; after labor, the anterior amniotic sac dilates the uterine opening and vagina; after rupture of membranes, amniotic fluid slides and flushes the vagina to reduce infection. The above briefly summarizes the growth process of the fetus baby in the whole pregnancy and ta “weaponry”, pregnant mothers, ready to oh, open this wonderful journey of life!
