Which statement defines nephrology?

• A. The branch of medicine that studies the brain; the study of brains
• B. The branch of medicine that studies the liver; the study of livers
• C. The branch of medicine that studies the kidneys; the study of kidneys
• D. The branch of medicine that studies the heart; the study of hearts

Answer: (C)

Medical terminology uses prefixes to point to an organ and the suffix -logy to mean "the study of." Nephro- refers to the kidney, so nephrology is the branch of medicine that studies the kidneys. That makes it the correct description. It's distinct from other organ-focused fields: neurology for the brain, hepatology for the liver, and cardiology for the heart. Nephrology specifically deals with kidney function, diseases, and medical management (like electrolyte balance and kidney-related disorders), rather than surgical aspects handled by other specialties.
