What is menstruation!
In the ovaries is a painChoe number of small clusters of cells called follicles. They mature egg.
The adult girl on a monthly basis on the right or left ovary matures one follicle, which begins to gather fluid, the follicle expands, its walls are stretched until it breaks. The egg with the liquid viporskuetsya from the ovary enters the fallopian tube and begins to move to the uterus. The moment of rupture of the follicle and release of the egg it is called ovulation.
This process takes place in the middle of the menstrual cycle, that is 11-14 days, counting from the first day of the end of the previousFirst menstruation. We must remember that these days most favorable for fertilization and probable (for those who want to avoid pregnancy, these days, on the contrary, the most dangerous, if not to take action).
On the site of the ruptured follicle, there is little bleeding and there is the so-called corpus luteum. Yaitsekletka same ejected from the ovary during ovulation, can be fertilized if the woman has sexual relations. It happens that at the time of ovulation, blood appears in detail about this on the website:.
fertilization, that is a fusion of female and male germ cells takes place in FallotPieve pipe on the way of the egg to the uterus. And if fertilization has occurred, the egg continues its path through the tube to the uterus, which lasts for 4-6 days. During this time, the fertilized egg consumption material, in particular glycogen, pyruvic acid, allocated Pipe secret, and thus, though gaining ground. This processcalled capacitation - a very important period of the existence of an early entry of a new life, which largely determines the further development of the fetus. Depends on the state of capacitation of the reproductive system, the activity of the secretion of the fallopian tubes and the content of the secret of its nutrients, which consumes a fertilized egg.
Inendometrium and the cyclic changes occur. Before the start of menstrual endometrium swells, it increases the secretion of glands and blood supply. The mother secret very rich in proteins and various enzymes, in the case of fertilization is also important for the fetus. At 6-8 day fertilized egg regard vnutrennega layer of the uterus - the endometrium, which is already prepared for this meeting, abundant growth of small blood vessels, and it deepens it. This point is called implantation, and it means that a pregnancy.
If fertilization has occurred, the egg dies, the surface layermucous membrane of the uterus (the endometrium) is torn away, torn blood vessels and bleeding occurs. Then the mucous membrane is reduced, then again slowly beginning to abound, to grow, to enrich the network of capillaries and so on until the next menstrual period.
