What circulatory system of vessels provides the heart with energy with its own blood supply for nutrients and oxygen?

The circulatory system that supplies the heart with its own blood supply is known as the coronary circulation. This system consists of the coronary arteries, which branch off from the aorta and deliver oxygen-rich blood to the heart muscle, and the coronary veins, which carry deoxygenated blood away from the heart. This dual system ensures that the heart receives the necessary nutrients and oxygen to function effectively.
