Which of the following structures is not part of the female reproductive system?

The bladder is not part of the female reproductive system; instead, it is part of the urinary system. The primary function of the bladder is to store urine before it is excreted from the body. In contrast, the ovary, uterus, and oviduct are all integral components of the female reproductive system.

The ovaries are responsible for producing eggs and hormones such as estrogen and progesterone. The uterus is where a fertilized egg implants and develops into a fetus during pregnancy. The oviduct, also known as the fallopian tube, is the structure through which the egg travels from the ovary to the uterus; it is also the site where fertilization typically occurs. Understanding these roles clarifies how the urinary and reproductive systems serve different functions in the human body.
