Final answer:

Veins have the lowest blood pressure due to thinner walls and larger lumens, facilitating smooth blood flow.

Veins have the lowest pressure among the blood vessels. As blood passes through capillaries and enters venules and veins, the pressure exerted by the heart contractions diminishes significantly due to thinner walls and larger lumens, allowing for more blood flow with less resistance.
