APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Veins comprise valves, which prevent the backward flow of the blood. The valves are bicuspid, that is, they comprise two flap-like compositions. In the veins, the valves ensure that the flow of blood takes place only in one direction. On the other hand, arteries carry oxygenated blood away from the heart.

Detailed explanation-2: -Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.

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.
