Arteries (from Greek á¼ÏÏÎ·ÏÎ¯Î± (artÄria) , meaning windpipe, artery) are blood vessels that carry blood away from the heart. While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries.hey carry blood that is oxygenated after it has been pumped from the heart. Arteries also aid the heart in pumping blood. Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation.
