Final answer:
Eggs move to the uterus through the fallopian tubes, where finger-like projections called fimbriae sweep the egg into the tube, and cilia and smooth muscle contractions transport it towards the uterus.
Step-by-step explanation:
Eggs, or oocytes, move to the uterus through the oviducts, also known as the fallopian tubes or uterine tubes. These muscular tubes extend from the uterus to the area near the ovaries. The ends of the fallopian tubes closest to the ovaries flare out into a trumpet-like structure with finger-like projections called fimbriae. After ovulation, the fimbriae sweep the released oocyte inside the tube. The inner walls of the oviducts are lined with ciliated epithelium and smooth muscle that work in concert to move the egg toward the uterus. Fertilization typically occurs within the fallopian tube if sperm reach the egg during this passage. The fertilized egg, now an embryo, will continue to travel towards the uterus where it can implant and develop.
