The heart is the only organ that pushes the blood to flow through the network of vessels or circulatory system and deliver the essential substances required for the survival of the body cells. But what about the cells of the heart itself? Can the blood just easily seep through the heart walls without the need of blood vessels?

The circulation of the heart mechanism, precisely at the aortic valves, flows blood to the left and right coronary artery and into the walls and septums of the four chambers and just like any other organs, when the vessel get narrowed or blocked it can cause ischemia and eventually chest pain (angina).
