Varicozitatilor and treatment of Couperose
What is a varicose vein?
Due to gravity, the blood always tends to circulate in the body from top to bottom. Blood circulation is done from the heart through the arteries to the legs, according to the law of gravity, and the legs to the heart through the veins, defying the law of gravity.
Arteries are equipped with strong muscular walls that contract rhythmically, pushing blood to the organs of the body and the legs.
The walls of the veins are thinner and the muscle wall is less developed. The veins are arranged so the surface of the skin of the feet, as well as in depth. There are thus two superficial networks: one that collects blood from the outer layers of the skin and deep, one of the larger veins, which collects blood from the superficial veins and then send to the heart. The deep venous system is surrounded by leg muscles which, by their contraction, help pushing blood through the veins into the heart, to the top. As the blood circulates in the opposite of gravity, there is the tendency to "fall" in the legs. To prevent this, the veins are provided from place to place with some valve like some cups with upward concavity, anchored to the wall of the vein and meet in the middle of it.
