Question Detail
Question
The ______ provides blood supply to the muscles of the heart.
Correct Answer
Option C is the correct answer.
Detailed Explanation
The coronary circulation is a system of blood vessels (coronary arteries and veins) that supply blood to and from the heart muscle itself. Pulmonary circulation deals with blood flow to and from the lungs, and systemic circulation supplies the rest of the body. Bisystemic circulation is not a standard term.
Hint
Think about the specific blood supply dedicated to the heart organ.
