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.
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.
No the heart pumps the blood but it does pump the blood through the arteries.
Because the arteries wouldn't be able to have blood flow through your body unlike arteries veins are through out your whole body so they can transport blood through your whole body, veins keep your blood circulating
blood travels away from the heart through arteries and blood travels to the heart through the veins

Arterial is a reference to the blood in the arteries, as opposed to blood in the veins.
through arteries
Blood is pumped by the heart.
blood travels away from the heart through arteries and blood travels to the heart through the veins
oxygenated blood
The blood runs through them
It is not true. Blood is also runs in arteries. Arteries take the blood throughout your body and veins take the blood back to your heart.
arteries are lined with smooth muscles
