Cause

The cause is still unknown and are usually benign. Some of the symptoms may include bruising, itching, swollen legs, and discoloration in blood vessels.

Difference Between Arteries, Veins, and Capillaries

Arteries are high pressure vessels that usually carry oxygen away from the heart to the rest of the body, which causes the layers of the vessels to be thicker than others. Veins are vessels that carry blood back to the heart, and are thinner since they do not have oxygen. Capillaries are the thinnest vessels, they connect arteries and veins together.

Back To the Heart

Some of the most important organs that blood flows through when going back to the heart is the kidney's and the liver. They are key for filtration and secreting the unneeded materials in the blood vessels.
