Question

Quizplus · Accepted Answer

Varicose veins occur when the valves within veins become damaged, causing blood to flow backward and pool in the vein. This pooling of blood leads to the vein walls becoming stretched and weakened, leading to the bulging and twisting associated with varicose veins. Increased osmotic pressure, damage to the venous endothelium, or an increase in hydrostatic pressure are not the primary causes of varicose veins.
