Coronary Arteries: Blood Supply to the Heart Muscle

The coronary arteries are the blood vessels that supply oxygenated blood to the heart muscle. There are three main coronary arteries: the left main coronary artery, the left anterior descending artery, and the right coronary artery. The left main coronary artery branches into the left anterior descending artery and the left circumflex artery. The left anterior descending artery supplies blood to the front of the heart, while the left circumflex artery supplies blood to the back of the heart. The right coronary artery supplies blood to the right side of the heart.

The coronary arteries are essential for the proper functioning of the heart. If the coronary arteries become blocked or narrowed, it can lead to a heart attack. A heart attack occurs when the heart does not receive enough oxygen-rich blood. This can damage the heart muscle and lead to heart failure.
