Arteries and veins have two different mechanism for maintaining circulation. Arteries are highly pressurized from the heart's ventricular contractions. Veins however are slower moving relying on the skeletal-muscle movement to help it along. Veins also have valves to control and keep flow in one direction.
Veins.
the type of blood vessels which flow contaminated blood to the heart are known as VEINS
veins

Capillaries.
Veins.
Blood vessels contract slightly to help the flow of blood As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body.
Veins. Veins are blood vessels that carry blood from tissues and organs back to the heart; they have thin walls and one-way valves.
Only veins contain valves. The valves prevent the backward flow of blood.
The blood flow distributed through you heart, veins, vessels, and arteries.
The vessels that pump blood round your body are called: veins, arteries and capilaries.
Arteries carry blood away from the heart. Veins carry blood to the heart.
