Arteries are tubes inside the body that carry blood away from the heart.
Arteries carry oxygen-rich blood to all parts of your body. Your biggest artery is the aorta, which starts at the heart and branches out. Your body uses the oxygen and carries the blood back via veins.
In the picture, the arteries are drawn in red.
