If the heart supplies blood to the whole body, what supplies it? No one thinks about this intriguing point. Well, except medical students😁 And the answer, in fact, is quite logical - the heart itself supplies itself with blood. What else... The first vessel that comes out of the heart is the aorta - at its very beginning, arteries branch off that go back and feed the heart. They are called coronary or coronary arteries. They wind around the heart like a crown or wreath - you can see in the animation. And just when the blood flow in these arteries stops or slows down a lot, the heart attack develops.
