The world literature has accumulated a considerable amount of data to characterize the main components of the female genital system, functional relationships between them, as well as the links between this system and other systems of the organism. The relevance of the study is also due to the fact that in the structure of female infertility 6070% is occupied by a tubo-peritoneal factor. The problems associated with this pathology have been studied for more than half a century. Until now, information about the microanatomy of the fallopian tube of a human and, especially, of the female white laboratory rat is contradictory. The aim of the study was to conduct a comparative analysis of the structural organization of the uterine tube of a human and female laboratory white rat. The article and analyzes the data of research conducted on 10 sexually mature white rats in females of reproductive age. The method of preparation was used, for the study of macroanatomy of the uterine tube of females, and also standard histological methods (cuts of the wall of the fallopian tube in the thickness of 5-7 microns, stained with hematoxylin and eosin). The external structure of the fallopian tube of the female rat and man has some differences. Unlike humans, the fallopian tube of a white laboratory rat has the appearance of a thin and short tubule, spirally twisted into a compact lump. In the fallopian tube of the female white rat, it is advisable to distinguish 2 parts: the funnel and the fallopian part. The uterine part connects to the uterine horn cavity of the uterine opening of the fallopian tube, and the fallopian tube opens into the cavity of the peritoneum to the surface of the ovary by the abdominal opening of the fallopian tube. Around the funnel of the fallopian tube, its mucous membrane is gathered in folds - the fringe of the fallopian tube and the ovarian fringe (in humans - one ovarian fringe), which are attached to the ovary. The diameter of the fallopian tube of the female white rat decreases in the direction from the funnel to the uterine part. In particular, in the area of the funnel, the diameter of the fallopian tube is 0.90±0.10 mm, and the diameter of the fallopian part is 0.70±0.09 mm. The uterine tube of a laboratory white rat, like a human, has a mesentery of the fallopian tube. Both in human and in female white rat, the wall of the fallopian tube consists of three layers: the inner lining is mucous, the middle lining is muscular, the outer lining is serous. It was established that the female uterine tube of a white rat in its macroscopic structure differs from the uterine tube of a person. The microscopic structure of human and the white rat female uterine tube is rather similar and, therefore, may serve as an object of the experimental modeling of certain pathological conditions of the reproductive system.
