What does the root word Cardi/o refer to?

Kidney
Liver
Heart
Lung

The correct answer is: Heart

The root word "Cardi/o" specifically refers to the heart. In medical terminology, many root words are derived from Greek or Latin, and "cardio" comes from the Greek word "kardia," which directly translates to "heart." This prefix is commonly used in various medical terms related to heart issues or the cardiovascular system, such as cardiology (the study of the heart), cardiovascular (pertaining to the heart and blood vessels), and others. Understanding the root words helps in deciphering medical terms related to their anatomical relevance, making "C. Heart" the correct answer.
