The blood in the veins is red, but appears to be blue, especially in older people, when seen through the skin.
arteries and veins are found throughout the body. arteries carry blood away from the heart and veins carry it to the heart
Veins tend to be more superficial, meaning they lie closer to the surface of the skin. Arteries usually, but not always, run deeper in the tissue than veins.
Superficial vein is a term used to describe a vein that is close to the surface of the body. It is used to differentiate veins that are close to the surface from veins that are far from the surface, known as deep veins. Superficial veins are important physiologically for cooling of the body. When the body is too hot the body shunts blood from the deep veins to the superficial veins, to facilitate heat transfer to the surroundings. Superficial veins can be seen under the skin.
Arteries are not close to the surface in most places on the body because they need to be protected. But there are many places, called endangerment sites, where they are close to the surface, so health care workers need to be cautious when working in these areas. Usually, in most place on the body arteries and veins are close together, so are nerves.
Arteries carry blood full of oxygen from the heart to your body's organs. Veins carry the blood back to the heart after the oxygen in the blood has been depleated by your body's organs. Since arteries are closer to the outlet of the heart, they also have a higher blood pressure than veins. It is also interesting to note that arteries tend to be closer to the core of your body, whereas veins tend to be closer to the outside surface of your body.
The largest vein in the body is the venae cavae. Veins are translucent so the color observed is the bloods color through the fat tissue. The veins contain 60 percent of the body's blood volume at any time.
The frontal surface of the body is the anterior or ventral surface of the body. Accordingly, the terms "anteriorly" and "ventrally" specify a position closer to--or toward--the frontal surface of the body.
Veins or arteries are close to the surface,
The smallest blood vessels are called capillaries. The next largest are veins. The largest are arteries. Arteries are deeper in the body than veins and capillaries, which are closer to the skin. Some veins are also deep within the body. There is no type of blood vessel starting with the letter "A" that is close to the skin.

It doesn't - it's the veins themselves that are blue.
it is closer to the core so there is less "pull" on the said body.
