Which combining form means "heart"?

nephro
cardio
hemo
pulmo

The correct answer is: cardio

The combining form "cardio" specifically refers to the heart. It is derived from the Greek word "kardia," meaning heart. This term is widely used in medical terminology to describe conditions, procedures, and diseases related to the heart, such as cardiology (the study of the heart) and cardiac arrest (a medical emergency involving the heart). Understanding this terminology is crucial for effective communication in a medical setting, especially in emergency care. In contrast, the other options correspond to different anatomical structures or systems: "nephro" refers to the kidneys, "hemo" relates to blood, and "pulmo" pertains to the lungs. Knowing these distinctions helps in accurately interpreting medical terms and provides a solid foundation for understanding anatomy and physiology relevant to emergency medical services.
