in most mammals their are two oviducts, they are they transport the secondary oocytes and fertilised ova from the ovaries to the uterus.
the oviducts are not just a passive pipe for transportation they are a active organ with different sections, each preforming a different function:
Fimbrial segment (information on alternate page)
infundibulum section (information on alternate page)
Amplullary segment this is the wide middle section of the oviduct
Isthmus this is a narrow muscular segment near the uterus
interstitial segment passes through the uterine muscle into the uterine cavity
function of all the above: the fimbria ovarica joins the fimbrial end of the tue and the ovary, at ovulation the fimbria contracts and this pulls the fimbrial end even closer to the oviduct,the fimbria capture the egg and draw it into the oviduct, muscular contraction of the tube and its cilia lining move egg and sperm towards the uterus, the interstitial segment prevents the egg from being released into the uterus until it is ready fro implantation, this journey time from egg release to implantation will be different in every species the above text is describing the human (Anon., 2014), (Tortora& Grabowski, Reynolds, 1996).
Horns of the uterus
the horns of the uterus (Uterotubal junction), the uterine horn is the part of the uterus the connects the Fallopian tube (oviduct), to the uterus its function is to serve as a pathway from the fallopian tube (oviduct)m to the uterus . in most mammal the reproduction system is key thus, so are the uterine horns, however each species will have its own size (the image is cat uterine horn), quantity and function of the horns, for example a dog who gives birth to many babies at once will have large uterine horns, whereas a human who produces typically one offspring at a time will have smaller uterine horns (Geek, 2014).
