Supply and demand. The coronary arteries regulate the supply of blood to your heart muscle depending on how much oxygen your heart needs at the time, as indicated by: 1  The number of times your heart beats per minute (heart rate). 2  Your blood pressure. 3  The force of your heart's contractions. 4  The thickness of your heart muscle.
Healthy arteries carry oxygen through the body. The adult heart pumps approximately 2,000 gallons of blood each day through an amazing, 60,000-mile-long network of arteries, veins and capillaries. Arteries are the blood vessels that carry oxygenated blood away from the heart to every organ in the body. In healthy individuals, arteries are clear, and blood can flow smoothly, but occasionally over time, they may develop a buildup of fatty deposits or plaque, commonly known as hardened or clogged arteries.
