The Fallopian tubes are tubes within the female body which play an important role in human reproduction. The ovum passes from the ovary to the uterus, by being gently swept along by cilia in the Fallopian tubes. The tubes are no bigger than a quarter in diameter and no longer than a candy cane (which they resemble in shape). An ectopic pregnancy is one that improperly occurs in the Fallopian tubes instead of the uterus.
