The study of the heart is called what?

• A. Cardiodynia
• B. Cardiology
• C. Cardiac
• D. Catabolism

Answer: (B)

The study of the heart is called cardiology. This term comes from cardio- meaning heart and -logy meaning study or science, so it names the medical field that focuses on the heart’s structure, function, and diseases, including diagnosis, treatment, and prevention. The other terms describe different ideas: cardiodynia refers to chest pain related to the heart, not the study itself; cardiac is an adjective meaning related to the heart; and catabolism refers to the metabolic breakdown of substances. So cardiology is the correct term for the field that studies the heart.
