Arteries have the highest blood pressure since they receive blood directly from the heart and must withstand the force of the contractions. Arterioles have a lower pressure than arteries but still contribute to the regulation of blood pressure. Capillaries have the lowest pressure, but largest surface area, allowing for the exchange of gases and nutrients between the blood and tissues. Venules and veins have even lower pressure than capillaries and return blood to the heart.
