Final answer:
The fallopian tubes connect the ovaries and uterus and are the site where fertilization typically occurs before the fertilized egg travels to the uterus for implantation.
Step-by-step explanation:
The structure that connects the ovaries and uterus is the fallopian tubes. These are narrow tubes that serve as the passage for oocytes (eggs) from the ovaries to the uterus. The fallopian tubes have an end with fimbriae that sweep the eggs into the tube from the ovary. Fertilization of the egg by the sperm typically occurs in these tubes, specifically within the ampulla, which is the middle region of the fallopian tube. A fertilized egg will then travel to the uterus and implant into its wall for development.
