Question

Quizplus · Accepted Answer

Varicose veins are caused by a failure of the venous valves, which are responsible for regulating blood flow and preventing blood from pooling in the lower limbs. When the valves fail, blood can pool and cause the veins to bulge and become swollen. Aneurysms or weak points in arteries or veins may also cause problems but are not specifically related to varicose veins. Failure of lymphatic valves is not related to varicose veins at all.
