The combining form orch/o refers to which organ?

The combining form orch/o refers to which organ?

• A. Testis
• B. Prostate gland
• C. Kidney
• D. Epididymis

Answer: (A)

Orch/o names the testis, the male gonad. This combining form appears in terms like orchitis (inflammation of the testis) or orchiectomy (removal of a testis), so it clearly points to the testis as the organ involved. The other options refer to different organs with their own stems: prostat/o for the prostate gland, nephr/o for the kidney, and epididym/o for the epididymis. Recognizing orch/o as the testis makes it the correct choice.
