One of your pulmonary veins does not take blood to your right ventricle.your pulmonary arteries on the other hand take blood from the right ventricle. They take the blood to the lungs to be oxygenated. There are four pulmonary arteries, two go to your left lung and two go to your right lung.All of your pulmonary veins takes blood to your left Atrium which then moves it into your left ventricle.

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").
