The blood flows through arteries because of the pressure generated by the heart and maintained by the action of the arterial muscles. Conversely, while veins also have a muscle, called the Tunica Media (the inner middle layer of the vein), aiding in propulsion of the blood flow through the heart, they must rely on internal valves to aid in propelling blood through them. Veins are a closed system, so they do not have the benefit of the pressure of the heart in propelling blood through them. The valves in veins assist in propusion of the blood through them and prevention of blood clots.
What else can I help you with?
Do veins carry blood at the same pressure as arteries?
No, veins carry blood at a lower pressure than arteries. Blood in arteries is propelled by heart contractions. Venous blood is propelled only by body movement and gravity.
Do arteries pump blood to your body?
No the heart pumps the blood but it does pump the blood through the arteries.
Why blood is transfused only through vein but not through arteries?

The blood runs through them
