      Hi Charlio!

      Thanks for your question! Yes it does! All our body is full of arteries, from big ones to small ones that get the oxygen and nutrients to all of our cells. However some cells like the neurons in the brain require more energy than say the legs so there are more arteries and veins in these regions to make sure there is always enough for our brain to work.
