Coronary arteries are blood vessels that supply oxygenated blood to the heart muscle itself. They originate from the aorta, the main artery that carries blood from the left ventricle of the heart to the rest of the body. The two main coronary arteries are the left coronary artery and the right coronary artery. The left coronary artery quickly branches into two smaller arteries: the left anterior descending artery and the left circumflex artery. These arteries form a network that wraps around the heart, ensuring that the heart muscle receives the continuous supply of oxygen and nutrients it needs to function. Blockages or narrowing within the coronary arteries, often due to plaque buildup (atherosclerosis), can lead to a reduced blood flow to the heart muscle, a condition known as coronary artery disease. This can manifest as chest pain (angina) or, in severe cases, a heart attack (myocardial infarction) if the blood flow is completely obstructed. Maintaining healthy coronary arteries is crucial for overall cardiovascular health.
