Explanation:
Detailed explanation-1: -Veins have thinner and less muscular walls. This is because veins have a lower level of pressure than arteries. So, their walls don’t need to be as thick to handle the pressure.
Detailed explanation-2: -Veins carry unoxygenated blood towards the heart, away from tissues at low pressure so the lumen is large. Blood moves more slower and often against gravity so valves and a larger lumen ensure it is still transported efficiently. Capillaries have the smallest lumen but relative to their size the lumen is quite large.
