The more kate learned about the process of fertilization, the more questions she came up with. She now understood that when released from a follicle, the oocyte enters the uterine tube. And that the follicle then begins to release hormones that signal the uterus that an oocyte is on the way. She also understood why women trying to get pregnant kept track of their temperature, as a rise in body temperature might indicate the presence of an oocyte in the uterine tube where fertilization could occur. But now she wondered how the oocyte traveled from ovary to the uterus. What best explains how an oocyte (whether fertilized or not) makes its way from the ovary to the uterus?.
