An artery (plural arteries) (from Greek á¼ÏÏÎ·ÏÎ¯Î± (artÄria), meaning 'windpipe, artery') is a blood vessel that takes oxygenated blood from the heart to all parts of the body. The two exceptions to this rule are the pulmonary and the umbilical arteries.
An artery is a blood vessel that conducts blood away from the heart. All arteries have relatively thick walls that can withstand the high pressure of blood ejected from the heart. However, those close to the heart have the thickest walls, containing a high percentage of elastic fibers in all three of their tunics.
