The prefix cardio- is associated with which body system?

Explanation:
Cardio- signals the heart and its role in moving blood, which is the core function of the circulatory system. In medical terms, cardio- is used in words like cardiovascular or cardiology to describe the heart and its vessels, tying directly to blood circulation throughout the body. The other systems aren’t described by cardio-—respiratory relates to the lungs and breathing, digestive to the gut, and nervous to the brain and nerves. So the best answer is the circulatory system because cardio- centers on the heart and blood flow.
