Varicose Veins And Spider Veins
The heart pumps blood to
supply oxygen and nutrients to all parts of the body.
Arteries carry blood from the heart towards the body parts,
while veins carry blood from the body parts back to the
heart. As the blood is pumped back to the heart, veins act
as one-way valves to prevent the blood from flowing
backwards. If the one-way valve becomes weak, some of the
blood can leak back into the vein, collect there, and then
become congested or clogged. This congestion will cause the
vein to abnormally enlarge. These enlarged veins can be
either varicose veins or spider veins...
