Coronary vessels are blood vessels that supply oxygen-rich blood to the heart muscle. They are essential for maintaining the heart's health and function. The main coronary vessels include the left coronary artery and the right coronary artery, which branch into smaller arteries to deliver blood to different areas of the heart. These vessels can become narrowed or blocked due to conditions like atherosclerosis, leading to reduced blood flow. This can result in chest pain or even a heart attack. Maintaining healthy coronary vessels is crucial for overall cardiovascular health and can be supported by a balanced diet and regular exercise.
