The combining forms hyster/o, metr/o, and uter/o refer to which body part?

• A. Lymph
• B. Jejunum (second part of small intestine)
• C. Uterus
• D. Potassium

Answer: (C)

These combining forms all refer to the uterus. Hyster/o comes from a Greek root meaning uterus, uter/o is another form of the same meaning, and metr/o is used in terms that denote the uterus (as in metrorrhagia, meaning uterine bleeding). So when you see these, think uterus and reproductive-tract context. The other options don’t fit because they refer to the lymphatic system, the jejunum portion of the small intestine, or an element/mineral, not a uterus.
