The fallopian tubes are also part of the direct communication between the inside of a woman's body (her peritoneum) and the outside via the vagina. Uhuh. The fallopian tubes open directly into the peritoneum.
On ovulation, the fallopian tubes actually move to overlap the ovary, in order to catch the ejected egg. The fallopian tubes are also the usual sites for sperm-egg union. The zygote is carried by the fallopian tube to the uterus where it usually implants.
An accidental implantation of the embryo in the fallopian tube results in an ectopic pregnancy, a potentially life threatening situation. |
