What is the muscular canal leading from the uterus to the outside of the body called?

The muscular canal leading from the uterus to the outside of the body is termed the vagina. This structure plays several essential roles in the female reproductive system. It serves as the passageway for menstrual fluid to exit the body, as well as the birth canal through which a baby is delivered during childbirth. The vagina also acts as the receptacle for the penis during sexual intercourse, facilitating reproduction.

In contrast, the urethra is a tube that carries urine from the bladder to the outside of the body but is not part of the reproductive system. The ovary is a reproductive organ that produces eggs and hormones but does not function as a canal. The fallopian tubes are responsible for transporting the eggs from the ovaries to the uterus but do not serve as a canal leading out of the body. Therefore, the vagina is the correct anatomical term for the structure in question.
