What structure serves as the narrow opening of the uterus?

Explanation:
The cervix is the narrow passage that forms the lower part of the uterus and connects to the vaginal canal. It contains the cervical canal and the external opening (the external os) that leads into the vagina, making it the actual narrow opening from the uterine cavity outward. The uterus above has a rounded fundus at the top, and the ovaries are separate glands that release eggs. The vagina is the canal that leads to the outside.
