H. Now locate the oviducts which lie beyond the uterine horns and adjacent to the ovaries. Note that there are 2 oviducts, one on each side of the tract. Each oviduct is composed of the: isthmus, ampulla, infundibulum, and ostium
The surface of the infundibulum is covered with the fimbria but they can not be resolved at this level of magnification. They capture the oocyte at ovulation and transport it to the ostium, the openning into the oviduct. The junction with the uterus is the uterotubal junction and the oviduct is supported by the mesosalpinx. Note that the oviduct was carefully spread out so that you could see all the structures. This is the right oviduct of this tract. Now view the oviduct on the left side of this tract.
