Arteries carry oxygenated blood away from the heart.
The muscular walls of arteries and arterioles keep blood flowing in one direction.

Explanation:

Arteries carry oxygenated blood away from the heart.

The initial movement of blood in the arteries is the pumping of the ventricle of the heart forcing blood into the aorta. The uni-directional flow of blood is maintained by the muscular walls of both the arteries and arterioles.

The pressure of these muscles in the arterioles is a major component of blood pressure.
