Magic of pregnancy, week after week. And what week do you have?

Беременность неделя за неделей

Pregnancy of a person (Latin graviditas) is a special condition of a woman's organism, in which her developing reproductive organs contain a developing embryo or fetus. Pregnancy occurs as a result of the fusion of female and male germ cells in the fallopian tube, after which a zygote containing 46 chromosomes is formed. The sex of the future child depends on a set of sex chromosomes (XX or XY), while the ovules are always carriers of the X chromosome, and the spermatozoa of the X or Y chromosome (in the ratio 1: 1). Thus, the sex of the future child is determined precisely by the sex chromosome, the carrier of which is the spermatozoon (in the case of the X chromosome, a female child is born, and in the case of the Y-chromosome, the male). As a result of cell division, a blastocyst is formed, which on the seventh day is attached to the uterine wall. In the first three months of pregnancy (first trimester) the fetal organs are laid, by the end of the 12th week the placenta is completely formed. Through it the fruit receives nutrients and the final products of metabolism are removed. The duration of a person's pregnancy is 9 months, or 40 obstetric weeks (counted from the date of the last menstruation). In obstetrics, a physiological and pathological pregnancy is distinguished. Normally, any pregnancy ends with a generic act - a baby is born, and in the case of multiple pregnancy - twins (homozygous - identical or heterozygous - different).
