Question

why are veins closest to the skin?​

Answer 1

Explanation:

Skin Complexion and Thickness

This is a normal part of the aging process. Sometimes, the veins are apparent because they're closer to the surface of the skin. The veins in the legs – the veins responsible for carrying small portions of blood to the heart – tend to be closer to the skin.
