Answer:
artery and veins are the types of blood vessels in our body

arteries do not possess any type of valve because the flow of blood in them is bidirectional whereas in veins they possess valve to prevent the back flow of blood.
vein collapse when they have no blood because they are thin but arteries do not collapse because they are thick.
