Business Description
First, understand how veins and arteries are different. Arteries take blood from the heart to the muscles. Veins take the blood back from the muscles to the heart. Veins, unlike arteries, have one-way valves that keep the blood moving toward the heart. A varicose vein happens when the valve weakens or doesn’t work well. The blood in the vein with the damaged valve backs up and makes bulges in the vein. To Know More Please Visit :- https://www.asksecondopinion.com/varicose-veins-treatment-prevention/
