Varicose veins are most commonly thought of as being located in the LEGS
Vagina Vagus nerve (stomach), veins, varicose veins, valves (heart), and the rest you know already.
collateral veins are produced by your body when it thinks it is not getting sufficient circulation from a part of the body. If a part of your body is not returning blood back to the heart from a particular part of the body, your body will grow veins around that area to assisst in circulating the blood. Unfortunately these veins are usually thinner and less organized than the original venous structures. Spider veins are examples of collateral veins. There are collateral arteries as well. When a part of the body is not receiving enough oxygen new arteries will grow around to assisst in circulation. Like veins these are of poor structural quality too.
There are two causes are there for the same probably. One is the pressure of the growing uterus on the abdominal veins. That increase the pressure in the leg veins. So they become tortuous. That is varicose. The other reason is related to increased level of pregnancy hormones. The exact contribution of the both is not known to me. You may ask the lady to sleep on the side to prevent the compression of the abdominal veins. But you can not ask her to maintain that position during the sleep.
You cannot intentionally increase the number of veins in your body. Veins are part of your circulatory system and are determined by genetics and your body's needs. Regular exercise and a healthy lifestyle can help maintain the health of your veins.

it supplies the heart and the brain
blood vessels which carry blood back to the heart from body regions.To understand vein disease, which is the primary cause of varicose veins, it's first important to understand the venous system of the human body. The venous system is the part of the circulatory system that returns deoxygenated blood through veins back to the heart to be recirculated. By contrast, the arterial system carries oxygenated blood away from the heart to be distributed throughout the body. The smallest parts of the venous system are the capillaries, which feed into larger superficial veins.
