State
An artery carries blood away from the heart through a thick, muscular, elastic wall built to withstand and smooth the pressure surges each heartbeat produces.
Show
An artery's elastic recoil between beats helps maintain forward flow while the heart briefly relaxes.
Watch for
"Artery" names a direction of flow, away from the heart — it does not specify what the blood contains.
