Answer

Brief Explanations:

Arteries transport oxygen - rich blood away from the heart to the body's tissues. Veins carry de - oxygenated blood back to the heart. Veins have valves to prevent back - flow of blood, while arteries do not need them as the high pressure of blood flow from the heart keeps blood moving forward. Arteries are thick, muscular, and elastic to withstand high blood pressure, while veins are less muscular. Capillaries connect arteries and veins.

Answer:

Arteries carry blood away from the heart; veins carry blood back to the heart.
