So this left ventricle forces all that blood to quickly fill this blood vessel. And that's exactly why this large artery contains a very high pressure because it's connected directly to that pump that establishes that high pressure in the first place. In fact, if we study the anatomy, the structure of the artery, arteries are made specifically to withstand these high pressures. They have a very thick layer of muscle within our tunica media layer of that artery. So large arteries and smaller arteries, they basically have a relatively high hydrostatic pressure because of this reason. Now, if we take a look at the following diagram, this is exactly what the diagram describes.
