What is the medical term that refers to the uterus?

The correct term that refers to the uterus is "hyster." This term is derived from the Greek word "hystera," which translates directly to "uterus." It is commonly used in medical terminology, especially in terms related to gynecology, such as "hysterectomy," which is the surgical removal of the uterus. Understanding the root "hyster" is important for recognizing various medical conditions and procedures involving the uterus.

In contrast, the other terms listed refer to different parts of the female reproductive system. The ovary is responsible for producing eggs and hormones, the vagina is the canal that connects the outer genitals to the uterus, and the fallopian tubes are the structures through which eggs travel from the ovaries to the uterus. Each of these plays a distinct role in the reproductive process, but none of them denote the uterus itself.
