Now that's because it's the ventricle that creates that hydrostatic pressure in the first place that forces all that blood to move into our blood vessel. And the blood vessels that connect directly to the left ventricle are these blood vessels. It's our order which is the largest artery in our body. 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.
