The superficial veins of the legs connect to the deep veins through "penetrating veins" which run perpendicular to the skin from one to the other.
The deep veins are essentially a column of blood running from your head to you feet and so when one is standing are under high pressure. In order to keep this pressure away from the frail superficial veins the penetrating veins have valves. When one of these valves goes bad the high pressure is allowed to go back to the superficial veins which blow up like balloons and become visible as what we call varicose veins (or "spider veins").
