So that's exactly why within veins we also have a low pressure and we also have a low velocity with which our blood actually moves. Now of course we have things like the valve system inside the vein and the skeletal muscle that allow that movement to actually take place. But that's a different story. So let's take a look at this diagram once again. The pressure is the Y axis. As we go from the large artery to the smaller arteries we have this very high pressure.
