What does a normal Fallopian tube look like?

A normal Fallopian tube is a slender, elongated structure, approximately 10-12 centimeters in length, that extends from the uterus to the ovaries. It is typically smooth and has a narrow lumen, lined with ciliated epithelial cells that help transport the egg from the ovary to the uterus. The tube consists of four parts: the infundibulum, ampulla, isthmus, and interstitial segment, with the ampulla being the widest section where fertilization often occurs. Its appearance can vary slightly, but it should be free of any blockages, adhesions, or abnormalities.
