Blood pressure in arteries is much higher than in veins. This may also receive blood from the heart after contraction, but it is also due to its ability to contract. The tunica media of arteries is thicker than veins and has smoother muscle fibers and elastic tissue.
Is blood pressure highest in veins and lowest in arteries?
Pressure is maximal in the aorta and gradually decreases as blood moves from the aorta to the large, small, and capillaries. The pressure is the lowest in the venous system, so blood collects in the veins and acts as a "blood reservoir".
Why does the pressure drop from the arteries to the veins?
Generally, blood pressure drops from arteries to veins due to pressure that overcomes the resistance of blood vessels. The greater the change in resistance at any point in the vasculature, the greater the loss of pressure at that point.
