Answer 2

Answer:

Explanation:

Unlike arteries, veins contain valvesthat ensure blood flows in only one direction. (Arteries don't require valvesbecause pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.
