And what that means is our veins are inelastic. They do not recoil. So they can easily expand when the blood enters these veins. And because they can easily expand, that decreases our pressure within the veins. On top of that, what also decreases is our flow, the velocity with which our blood actually flows. And on top of that, because veins have to move that blood against the force of gravity that will additionally decrease the flow velocity of our blood within veins.
