Veins vs. Arteries

Veins
Carry blood to heart
Thin walls and has valves
Usually near to the skin
Lower blood pressure
Arteries
Carry blood away from heart and to body tissues
Thick walls and lacks valves
Usually deeper than veins
Higher blood pressure
Why aren’t there varicose arteries?
Arteries do not become clogged as easily as veins do. They lack the valves that veins have because the blood in arteries does not have to fight against gravity. Arteries are not superficial like veins.

What Are Varicose Veins

Varicose Veins are generally very knotted and swollen veins that are usually found in the feet and legs. Blood is carried from the heart to the tissues by a system of arteries and returned to the heart by veins. Muscle contractions, generated by the muscular system and initiated by the nervous system, help the blood fight against gravity and get back to the heart. The Respiratory System also changes the pressure in the thoracic cavity which helps to suck blood back to the heart. Valves that are found in the veins open to allow allow blood to pass through, but close so that blood cannot flow backward. Sometimes, the valves do not close and blood is allowed to flow backwards and ends up pooling in the legs. Overtime, this build-up can cause the walls of the veins to become distended and swollen. The appearance of these veins is usually a leg that has bumps and is very gnarled.
