Which root means viscera?

• A. Enter/o
• B. Arthr/o
• C. Coron/o
• D. Viscer/o

Answer: (D)

The root that means viscera is viscer/o. It comes from the word viscera, referring to the internal organs—the stomach, intestines, liver, and other organs inside the body. When you see viscer/o in a term, it signals something related to those internal organs, for example visceral meaning pertaining to the viscera or the viscera themselves (the internal organs).

Other roots point to different parts: enter/o is about the intestines (as in enteritis or enteral), arthr/o is about joints (as in arthritis), and coron/o relates to the crown, used in terms like coronary, which often refers to the heart’s vessels but not to viscera as a group.
