Nice Legs! helps keep the blood flowing. Leg veins have the critical task of returning blood to your heart. Moving your legs helps blood move upward.
When standing, as much as 70% of the blood volume in your body may be in your legs. Leg veins have the critical task of returning this blood to your heart. Leg movement and the squeezing action of leg muscles helps blood move upward. Leg veins have small valves that prevent blood from following gravity back down towards your toes. As we age, walls of the veins may become weaker and become distended. When the veins stay stretched, the valves cannot close and blood pools in the veins. Varicose veins are distended veins that have lost some measure of their ability to help move blood back towards the heart.
