Which term relates to the kidneys?

• A. Renal
• B. Precaution
• C. Primary
• D. Prognosis

Answer: (A)

Medical terms that denote an organ relationship use specific descriptors. For kidneys, the standard descriptor is renal. Renal means of or relating to the kidneys and is used in everyday medical language to describe anatomy and function—renal arteries supply the kidneys, renal cortex is part of the kidney, and renal function tests assess kidney performance. The other options don’t pertain to the kidneys: precaution is about safety steps, prognosis is the expected course or outcome of a disease, and primary means first or main. So renal is the term that relates to the kidneys.
