The heart pushes blood to the arteries.... there's already some blood there from the last time the heart pushed blood in, so this blood gets pushed further away, which pushes the blood in front of it also further away, and so on and so on...
Since it runs in a closed circuit, eventually, the blood returns to the point of origin and restarts the cycle.

I think I once read that it takes about 50 heart beats for one full "lap"... but I may be mistaken!
