A member asked:
Why is blood pressure in artery higher than in vein?
A doctor has provided 1 answer
Higher flow, closer: The arteries get blood directly from the heart, which adds pressure to the blood pool in the left ventricle in order to get it to flow to the body. The veins "hold" blood for the heart to pump, & don't need much force. The arteries also have thicker, stiffer walls than the floppy veins, which allows them to "hold onto" the pressure more. For these reasons, arterial BP is higher than in the veins.
