Answer:
Explanation:Blood flows from the capillaries into very small veins called venules, then into the veins that lead back to the heart. Veins have much thinner walls than do arteries, largely because the pressure in veins is so much lower. Veins can widen (dilate) as the amount of fluid in them increases.

Answer:
due to thick walls of arteries and small lumen the volume decreases and hence pressure increases as volume and pressure are inversely realted.
