The female genital area is quite fragile, and from the slightest violations in it, various pathological processes arise that can lead to infertility – the biggest problem. Often this condition occurs due to problems in the fallopian tubes. In order to understand what processes are taking place here, you need to know their structure.

The structure of the fallopian tube
The fallopian tubes consist of four departments along their entire length. They move away from the body of the uterus almost horizontally and end in an extended fringed part, which is called the funnel. These widest parts of the tube are located in the immediate vicinity of the ovary, in which the egg is born and comes out on a certain day of the menstrual cycle to meet with the sperm.

Further, after the funnel, there is an ampullary section of the pipe – its rather wide part. After that, the uterine or fallopian tube gradually narrows, and this part of the isthmus is called isthmic.

The tubes end with the uterine part, where they pass into this muscular organ. The walls of the tubes differ in their structure – the outer layer is a serous membrane (peritoneum), the middle one consists of a longitudinal and circular layer of muscles, and the inner one is a mucous membrane collected in grooves and covered with ciliated epithelium, with the help of which the egg moves into the uterine cavity.

Fallopian tube size
The fallopian tubes, despite their important function, are very small. The length of one is from 10 to 12 cm, and the width (or rather, the diameter) is only 0.5 cm. If a woman has any disease of the fallopian tubes, then some increase in diameter is possible due to swelling or inflammation.

Fallopian tube function
Departments of the uterine tube Now we know what the fallopian tubes look like, but what exactly do they perform in the female body? As mentioned earlier, the egg, leaving the ovary during ovulation, is captured by the villi of the funnel of the tube and gradually moves along its canal towards the uterus.

On one of the segments of the journey, the egg, under favorable conditions, meets with the sperm and conception occurs, that is, the birth of a new life. Further, thanks to the lining of the inner villous epithelium, the fertilized egg moves into the uterine cavity, where after 5-7 days of travel implanted in her muscle layer. Thus begins a pregnancy that will last 40 weeks.
