Which structure is a tubular portion of the reproductive tract that extends from the outer opening to the cervix?

• A. Ovary
• B. Vagina
• C. Fallopian Tube
• D. Uterus

Answer: (B)

The vagina is the tubular canal that runs from the external vaginal opening to the cervix. It is a muscular, elastic passageway forming part of the female reproductive tract, and it serves as the route for menstrual flow, intercourse, and childbirth. The other structures aren’t tubes extending from the outside to the cervix: the ovaries are glands that release eggs, not a canal; the fallopian tubes connect the ovaries to the uterus but do not extend from the outside to the cervix; and the uterus is the organ above the cervix, not a canal leading to the outside.
