Detailed explanation-1: -They are larger and hold more blood than the arteries. The blood passing through the veins is deoxygenated (except in pulmonary veins ) and flows at a low pressure. It flows slow and steady against the direction of gravity. Therefore, veins have valves to prevent the backflow of blood.
Detailed explanation-2: -What are Venous Valves? Venous valves are flap like structures that control blood flow in the deep veins. To ensure vein health, learn about the functionality of and potential problems with the venous valves of the deep veins.
Detailed explanation-3: -Many veins, particularly those in the arms and legs, have one-way valves. Each valve consists of two flaps (cusps or leaflets) with edges that meet. Blood flowing toward the heart pushes the flaps open like a pair of one-way swinging doors.
