Final answer:
The female equivalent to the ductus deferens is the fallopian tube, which serves as the conduit for the oocyte from the ovary to the uterus. It is posterior to the ureters in relation to the crossing point.
Step-by-step explanation:
The female equivalent to the ductus deferens is the fallopian tube.
The fallopian tubes are located near the ovaries and serve as the conduit for the oocyte (egg) from the ovary to the uterus. They consist of three sections: the isthmus, ampulla, and infundibulum. Fertilization of the egg usually occurs in the ampulla of the fallopian tube.
The fallopian tubes are posterior to the ureters in relation to the crossing point.
