An artery is a blood vessel that carries blood away from the heart.
Most arteries carry oxygen-rich blood to the body’s tissues, although the pulmonary arteries carry oxygen-poor blood from the heart to the lungs.
Arteries have thick, elastic walls that help withstand the high pressure generated by the beating heart.
