How the conception of a child occurs is not known to every person. Although a lot of articles, lessons at school, in higher education institutions, especially medical ones, are devoted to this issue. So how is the conception of a child? Let's consider in more detail later in the article.
The birth of life is an amazing process. It begins with the fertilization of the maternal egg with the father's sperm. During intercourse, millions of spermatozoa rush to the egg. However, only one of them fertilizes her. The sperm penetrates through the membrane of a mature egg rather quickly. After that, the other sperm can in no way be able to do the same. At the same time, only its head penetrates the egg, while the tail remains outside. This part later collapses.
At the moment when the head of the male sperm entered the egg, its chromosomes and the egg itself merge into one. That is why the number of chromosomes in the newly formed new cell becomes forty-six. As a result of this process, the so-called zygote is formed, moving into the uterine cavity from two to three days. For a long time, the zygote divides, a blastula is formed.
The new cell has several layers. The top layer is called trophoblast. It secretes special special enzymes. They are able to dissolve the layer directly in the uterus. Subsequently, a certain depression forms. As a result, the fetal egg itself will be immersed in this depression . Specialists call this process implantation. A familiar word for many people, its meaning in different situations is changing. If you count by day, then in this case, implantation occurs about the seventh day after the fertilization of the egg. If up to this point any harmful effect has been exerted on the egg, it dies or is damaged in some places. However, after that its full recovery is possible.
Subsequently, the fetal membrane forms from the trophoblast. There are several of them, one of these shells is called chorion. Chorion has villi, with the help of which the placenta is then formed. Her education begins at the eighth week of pregnancy. As for its full formation, this period falls on the fourteenth week. The placenta is of great importance in the development of the child. This is an organ that will function until the birth and birth of the baby. In general, the appearance of this placenta is very similar to an ordinary cake. Its diameter is twenty to twenty-five centimeters, while its thickness is only one and a half to two centimeters.
Many vessels go from the placenta to the developing fetus. They are surrounded by a special substance. This is the umbilical cord. It is the placenta that represents a system that performs many functions in the life of the fetus. These are the lungs, and the liver, and the kidneys for a growing organism. In addition to all this, nutrients come to the fetus through it, products of the fetal metabolism come out, vital gas exchange is carried out. The placenta provides normal uteroplacental circulation.
How is the conception of a child described above. It is worth noting that today anyone can purchase or study a huge amount of information on this process.
