What medical root refers to the heart?

The correct root that refers to the heart is "Card/i." This prefix is derived from the Greek word "kardia," which directly translates to "heart." In medical terminology, "Card/i" is commonly used in various terms related to the heart, such as cardiology (the study of the heart) and cardiovascular (related to the heart and blood vessels).

While the other roots are associated with the cardiovascular system, they have more specific meanings. "Coron/o" refers to the coronary arteries and structures surrounding the heart. "Myocardi/o" pertains specifically to the heart muscle, with "myo" meaning muscle and "cardi" meaning heart. "Angi/o," on the other hand, refers to blood vessels in general, and does not specifically denote the heart itself. Understanding these specific meanings helps to grasp how medical terminology communicates detailed information about the cardiovascular system.
