Arteries supplying blood to the heart are called
Explanation
Correct answer: option 3 — coronary arteries. The coronary arteries are the vessels that supply oxygen-rich blood to the heart muscle (myocardium); they wrap around the heart and deliver blood into the heart’s muscle tissues and conduction structures [1]. Two principal coronary arteries (left and right) arise from the base of the aorta and branch to perfuse the atria, ventricles, and nodes, providing the myocardium’s oxygen and nutrient supply [2]. The other options refer to vessels for different organs: the carotids supply the head/brain [3], hepatic arteries serve the liver, and the pulmonary artery carries blood between the heart and lungs (primarily deoxygenated blood) [4].
