Verified step by step guidance

Understand the process of fertilization: Fertilization occurs when a sperm cell meets and fuses with an egg cell to form a zygote. This typically happens within the female reproductive system.
Identify the structures involved in the female reproductive system: The key structures include the ovaries, uterine (fallopian) tubes, uterus, cervix, and vagina. Each structure has a specific function in reproduction.
Focus on the uterine (fallopian) tube: The uterine tube is a pair of narrow tubes that connect the ovaries to the uterus. It is lined with ciliated cells that help transport the egg from the ovary toward the uterus.
Explain why fertilization occurs in the uterine (fallopian) tube: After ovulation, the egg is released from the ovary and enters the uterine tube. Sperm cells travel through the vagina, cervix, and uterus to reach the uterine tube, where fertilization typically occurs.
Clarify the roles of other structures: The ovary produces and releases the egg, the cervix acts as a gateway to the uterus, and the vagina serves as the entry point for sperm during intercourse. However, these structures are not the site of fertilization.
