The oviduct, also known as the fallopian or uterine tube, is a tube-like structure in female animals, including mammals. It serves as a passageway for the transportation of eggs from the ovary to the uterus or exterior. The oviduct plays a crucial role in reproduction, as it is the site where fertilization between an egg and sperm typically occurs. The walls of the oviduct are lined with ciliated cells and muscular layers, which aid in the movement of the egg toward the uterus. In addition to providing a pathway for the egg, the oviduct also provides a suitable environment for fertilization and early embryo development.
