COMPARATIVE ANATOMY OF THE BLOOD SUPPLY OF THE FEMALE REPRODUCTIVE SYSTEM OF HUMANS AND RATS

Abstract

Impaired blood supply to the female reproductive system can lead to serious health problems for women, including infertility.The fallopian tube, also known as the fallopian tube, is an important part of a woman's reproductive system because it connects the ovary to the uterus. It is here that fertilization of the egg by the sperm occurs.The reproductive system of white rats shares many features with the female reproductive system, including variations in the placement of arteries and veins in the internal genitalia.The aim of our study was to describe variations in the location and features of the blood supply to the internal genital organs of a normal female laboratory rat, and to compare the anatomical features of the location of arteries and veins in rats and humans.Materials and methods. The study was performed on 10 sexually mature female white rats, aged 4.5–6.0 months and weighing 180–220. The method of preparing corrosive preparations of the vascular bed of the internal genital organs of a female white laboratory rat was used.Results of the study: it was established that the main sources of blood supply to the internal genital organs of the female white rat are the uterine and ovarian arteries. The ovarian artery departs from the cranial mesenteric artery, which is a branch of the abdominal aorta. In one of the female laboratory rats, the ovarian artery departed from the renal artery. The arteries of the genital organs are accompanied by corresponding veins. The venous system of the genital organs is very well developed. The total length of the venous vessels significantly exceeds the length of the arterial ones due to the large number of venous plexuses that anastomose with each other. A feature of the right ovarian vein is that this vessel flows into the inferior vena cava, and the left one into the renal vein. Conclusions: the blood supply to the internal genital organs of the female white rat has significant similarities to the blood supply to the organs of the human reproductive system, which allows the use of such animals in modeling various pathological conditions of the female reproductive system in scientific research.
