The term "cardio" relates to which part of the body?

  1. Liver

  2. Brain

  3. Heart

  4. Kidney

The correct answer is: Heart

The term "cardio" is derived from the Greek word "kardia," which means heart. In medical terminology, "cardio" is commonly associated with anything related to the cardiovascular system, including the study of heart function, heart diseases, and procedures or interventions involving the heart. For example, cardiology is the branch of medicine that deals with disorders of the heart, and cardiovascular health refers to the health of the heart and blood vessels. This connection between "cardio" and the heart solidifies the understanding that any references to "cardio" pertain specifically to this vital organ's function and health.
