After ovulation, the mature ovum enters which structure first?

Explanation:
After ovulation, the mature oocyte is released from the ovary into the peritoneal cavity and is quickly guided into the lumen of the fallopian (uterine) tube by the fimbriae. The uterine tube is the first structure the oocyte enters, where it then begins its journey toward the uterus (fertilization typically occurring in the ampulla region). The other options are not the first place the oocyte enters after release—it's not released back into the ovary, nor does it enter the cervix or vagina at this stage.
