But the walls of the veins cannot actually push back the same way that the arteries can. And that's exactly why when the blood flows through the veins, that increases the volume of our vein and the veins can actually push back. They cannot recoil back. And so we say that veins have a high compliance. So veins behave very differently than arteries. When they experience blood flow, the blood pushes on the walls, but the walls cannot actually push back as well.
