7. Arteries are blood vessels which deliver oxygen rich blood from the heart to the tissues of the body. Its structure is specialized with a muscular tube lined by smooth tissue which has three layers (see images below): Artery walls contain muscle cells so that they can change blood flow and blood pressure by either contracting or relaxing.
