veins, arteries and capillaries are all called blood vessels or blood streams.
When travelling from legs to heart, blood travels in veins. These veins have a special structure which is adapted for this type of transport. They have valves or pocket-like flaps which prevents blood from flowing backwards or in other words, falling down.
