The fallopian tubes are two thin tubes in a woman's body that connect the ovaries to the uterus. They play a crucial role in reproduction by allowing the egg released from the ovary to travel toward the uterus. If sperm is present, fertilization can occur in the fallopian tube, leading to the formation of an embryo. Each fallopian tube is about 10 centimeters long and lined with tiny hair-like structures called cilia, which help move the egg along. If the egg is not fertilized, it will eventually be absorbed by the body or exit during menstruation, while the uterus prepares for a potential pregnancy.
