'Orchi/o' is a term used to refer to which organ?

The term 'Orchi/o' specifically refers to the testes. This prefix is derived from the Greek word "orkhis," which means testicle. In medical terminology, it is commonly used in words related to the testes and male reproductive health, such as orchiectomy (surgical removal of one or both testes) and orchitis (inflammation of the testes). Understanding this term is essential for accurately discussing male reproductive anatomy and various medical conditions associated with it. In contrast, the other options represent entirely different anatomical structures and do not relate to the term 'Orchi/o.'
