3 key facts to remember about blood vessels:

1- Arteries carry blood from the heart at high pressure; they have thick, elastic walls to handle that pressure.

2- Capillaries have very thin walls in order to allow essential molecules to diffuse in and out of the blood into the tissue fluid.

3- Veins cary blood under negative pressure back to the heart; they have thin, inelastic walls so that they don't collapse, and valves that prevent backflow.
