How is the conception of a child

How the conception of a child occurs is not known to every person. Although many articles, lessons in the school, in higher education, especially medical, are devoted to this issue. So how does a child conceive? Let's consider in more detail in the article.

The birth of life is an amazing process. It begins with the fertilization of the mother egg with the sperm of the father. During sexual intercourse, millions of spermatozoa migrate to the ovum. However, only one of them impregnates it. Through the shell of a mature egg, the spermatozoon penetrates rather quickly. After that, the other spermatozoon will not be able to do the same thing in any way. In this case, only the head penetrates into the egg, the tail remains outside. This part is later destroyed.

At the moment when the head of the male sperm entered the ovum, its chromosomes and the egg itself merge into one. That is why the number of chromosomes in the newly formed new cell becomes equal to forty-six. As a result of this process, a so-called zygote is formed, moving into the uterine cavity for two to three days. For a long time the zygote is divided, a blastula is formed.

The new cell has several layers. The upper layer is called trophoblast. It emits special special enzymes. They are able to dissolve the layer directly in the uterus. Subsequently, a certain deepening is formed. In this groove the result will be immersed itself a fetal egg. This process is called implantation by specialists. A familiar word for many people, its meaning varies in different situations. If counted by days, then in this case the implantation occurs approximately on the seventh day after the fertilization of the oocyte. If up to this point the egg has been exposed to any harmful effect, it dies or is damaged in some places. However, after this, its full restoration is possible.

Later on, a fetal membrane forms from the trophoblast. There are several of them, one of these shells is called chorion. Chorion has villi, which then forms the placenta. Her education begins on the eighth week of pregnancy. As for its full formation, this period falls on the fourteenth week. Placenta is of great importance in the development of the child. This is the organ that will function before 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.

From the placenta to the developing fetus, there are many vessels. They are surrounded by a special substance. This is the umbilical cord. It is the placenta that is a system that performs many functions in the life of the fetus. These are the lungs, liver, and kidneys for a growing body. In addition, through it nutrients are suitable for the fetus, the products of the fetal metabolism are released, vital gas exchange is carried out. The placenta provides a normal utero-placental circulation.
