fallopian tubefallopian tube(fəlō`pēən), either of a pair of tubes extending from the uterus to the paired ovaries in the human female, also called oviducts, technically known as the uterine tube. At one end the long, slender fallopian tube opens into the uterus; the other end expands into a funnel shape near the ovary. The epithelium that lines the tube is covered with cilia that beat continuously toward the uterus. When an ovum is expelled into the peritoneal cavity from the ovary during ovulation, it is propelled into the wide-mouthed opening of the fallopian tube, through the tube, and into the uterus by the wavelike motion of the cilia. If the ovum is fertilized, an event that normally takes place in the fallopian tube, and the embryo (fertilized ovum) implants in the tube, or another area outside the uterus, an ectopic pregnancy occurs. About 98% of ectopic implantations occur in the tubes, but other sites include the abdomen, ovary, and cervix. Immediate surgical removal of the products of conception is necessary to prevent hemorrhage and other complications resulting from ectopic pregnancy. The fallopian tubes are also the site of the most common surgical procedures used to prevent conception or cause infertility in women. Usually the tubes are tied off in a procedure known as tubal ligation, although they are also sometimes excised or occluded by other methods.

The Fallopian tube extends from the ovary to the uterus and transports ova from the ovary to the cavity of the uterus. Each tube is about 5 in. (12.5 cm) long; one lies on either side of the uterus and is attached at the upper portion. Each curves outward to end in a hoodlike opening, the infundibulum, with many fingerlike projections; the cavity of the Fallopian tube is continuous with the cavity of the coelom. The ovaries lie below and inside the tubal curve. The ovum remains viable in the oviduct for about 1–3 days only. If fertilization occurs, the ovum moves into the cavity of the uterus and then implants on its wall. If fertilization fails to occur, the ovum degenerates in the uterus. Occasionally, a fertilized ovum fails to enter the uterus, or may be freed into the abdominal cavity, so that an ectopic pregnancy results if the ovum finds a site for implantation. See Reproductive system Fallopian tube[fə′lō·pē·ən ′tüb]Fallopian tubefallopian tube[fah-lo´pe-an]When the mature ovum leaves the ovary it enters the fringed opening of the fallopian tube, through which it travels slowly to the uterus. When conception takes place, the tube is usually the site of fertilization. Obstruction or infection within the fallopian tubes is a major cause of infertility. The removal of one tube by surgery, or the failure of a tube to function, ordinarily leaves the other tube intact and able to perform its function in reproduction. Occasionally the fertilized ovum implants in the wall of the fallopian tube, resulting in an ectopic, or tubal pregnancy.  u·ter·ine tube[TA]fallopian tubealsoFallopian tube(fə-lō′pē-ən)u·ter·ine tube(yū'tĕr-in tūb) [TA]Synonym(s): salpinx (1) [TA] , fallopian tube, gonaduct (2) , oviduct. Fallopian tubeThe open-ended tube along which eggs (ova) travel from the ovaries to the womb (uterus) and in which fertilization must occur if pregnancy is to result. The open end of each Fallopian tube has finger-like processes that sweep over the surface of the ovary at the time of ovulation, wafting the egg into the tube. Also known as a uterine tube. (Gabriele Fallopio, Italian anatomist, 1523–63).Fallopian tubea tube forming part of the OVIDUCT, present on either side of a female mammal, that transmits secondary oocytes from the peritoneal cavity to the uterus and is the usual site of FERTILIZATION. Ciliary action is involved in the egg movement, and muscular action of the uterus facilitates the upward movement of sperms from the vaginal tract where they have been deposited after copulation.Fallopian tubeFallopius,Gabriele, Italian anatomist, 1523-1562.Patient discussion about Fallopian tubeQ. She had an infection in her fallopian tubes. She is recovering now, but can she get pregnant again? My sister had a very bad pregnancy where she had lost her first child. She had an infection in her fallopian tubes. As it was an ectopic pregnancy, she had an operation where they made a small incision in the fallopian tube and removed the embryo. She was depressed for quite a while as she was looking forward to enjoying her new baby. She is recovering now, but can she get pregnant again? Fallopian tube
