Moving blood to and from the heart
Veins are responsible for the movement of deoxgenated blood from the heart
It's responsible for the beating of the heart and closing of valves in the veins of the legs.
The veins and arteries.
The veins responsible for returning blood to the heart are the Superior and Inferior Vena Cava. Arteries send blood away from the heart, going from Arteries to Arterioles to Capillaries, then the return is from Capillaries to Venules to Veins. The Superior and Inferior Vena Cava are the veins that send blood to the right atrium after an entire blood circulation cycle.
Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart
veins are responsible for bringing blood back to the heart.

No. Veins are the portion of the circulatory system that is responsible for returning blood from the body to the heart. Thus blood flow in veins starts at the smallest capillary vessel and moves to larger vessels.
Veins are blue in color, they carry deoxygenerated blood which has greater absorption coefficient than the oxygenated blood that runs in artery which is mainly responsible for the blue color.
