No, you do not have to. They should still be there before and after heart surgery.
If they are big and kind of stick out a little, they might be varicose veins. Lower extremity veins normally have valves in them to help pump blood from the legs back to the heart. In varicose veins, these valves have stopped working. Varicose veins can be potentially dangerous and can lead to blood clots. I'm pretty sure surgery is the only fix.
no. putting legs up can prevent new ones. only surgery can remove those veins.
The generic term is sclerotherapy and includes such cosmetic procedures as the removal of varicose or "spider" veins from the legs.
blood can still return via the deep veins
The muscles in your legs help transport blood back to your heart. The veins in your legs also have valves to help this process and prevent blood from flowing back down towards your feet.
Elevating your legs can help with varicose veins by reducing swelling and improving blood flow. When you elevate your legs, gravity helps to move blood back towards the heart, reducing pressure in the veins and alleviating symptoms like pain and swelling associated with varicose veins.
It's responsible for the beating of the heart and closing of valves in the veins of the legs.
Yes, pigs have veins in their legs just like other mammals. Veins are part of the circulatory system that carries deoxygenated blood back to the heart.
yes
Regeneration
Some amphibians can. Salamanders can grow back legs, tadpoles can regrow broken tails, but frogs can't grow back legs. i am dating a hot guy!
Muscular contraction in the extremities moves the blood through the veins, the valves only allow blood to move toward the heart.
