kransæðarnar

Kransæðarnar are the coronary arteries, a pair of blood vessels that supply oxygen-rich blood to the heart muscle. The left coronary artery and the right coronary artery branch off from the aorta, the main artery leaving the heart. The left coronary artery further divides into the left anterior descending artery and the left circumflex artery, which together supply the front and side of the heart. The right coronary artery typically supplies the right side of the heart and the back of the left ventricle. These arteries are crucial for the continuous function of the heart, ensuring the myocardium receives the oxygen and nutrients it needs to pump blood throughout the body. Blockages or narrowing of the kransæðarnar, often due to atherosclerosis (plaque buildup), can lead to conditions like angina (chest pain) and myocardial infarction (heart attack). Maintaining healthy kransæðarnar is vital for cardiovascular health.
