Detailed animation video explaining the whole process of fetal development
The development of a fetus in the womb is a complex and magical process, gradually developing from a single cell into a small living body. There are many aspects of this process worthy of our attention and research. The following will explain in detail the entire process of fetal development in the womb from four aspects.
The first aspect: embryonic stage
The embryonic period begins with the formation of a fertilized egg and usually lasts 2 weeks. During this stage, the fertilized egg gradually divides into dozens of cells with the support of protein secretion in the uterus. After 14 days, the fertilized egg develops into a sac-like embryo, which already has the primitive form of the nervous system, cardiovascular system and internal organs. The embryo begins to prepare to differentiate into the somatic stem layer and endoderm in order to focus more on the development of different organs and tissues during future development.
The second aspect: placental stage
The placental period usually lasts from 14 days to 8 months after pregnancy. During this period, the fetus begins to enter the real development stage. The fetus continues to grow every day as the membrane sac expands, and the surrounding placenta is also constantly evolving to provide adequate nutrients and oxygen to the fetus. The placenta plays the role of maternal-fetal communication at this stage, forming a close connection with the mother\’s body.
The third aspect: the last few weeks before birth
At 32 weeks after pregnancy, the fetus\’s main organs and tissues have completed development, but at this stage the fetus is still growing evenly, constantly absorbing and converting it into fat and storing it in the body. This period occurs around the physician\’s scheduled due date. The closer to the due date, the pregnant woman will begin to feel the slight movement of the baby\’s shrinkage, and observe the baby\’s heartbeat and fetal movements. After the due date arrives, under the intense contractions and labor pains, the fetus begins to shrink its body so that it can easily pass through the reproductive tract and be born into the world.
The fourth aspect: neonatal period
The neonatal period refers to the time within the first month after birth. After babies are born, doctors will perform a series of tests on them to check whether they are healthy, have any physical defects, and whether they need special care. During the newborn period, a series of changes will occur in the baby\’s important physiological indicators such as body temperature, heart rate, and breathing. During this period, the child will gradually get used to living outside and adapt to the mother\’s feeding.
Summary
The entire development process of the fetus in the womb is a process full of surprises and changes. The four aspects of content include four different time periods: the embryonic stage, the placental stage, the last few weeks before the fetus is born, and the neonatal period. It explains in detail the developmental changes and important physiological indicators of the fetus during these time periods. . We introduced the baby\’s development process in simple terms, presenting a clearer picture to everyone and increasing their understanding of the importance of protecting the baby.
