📝 Essential Points

• Arteries have a smaller lumen compared to veins of similar size.
• Veins have thinner walls and larger lumens to accommodate larger blood volume.

💡 Key Takeaway

Structural adaptations of artery and vein walls reflect their functional roles in circulation, with arteries built to withstand higher pressure and veins designed to hold larger blood volumes with valves to prevent backflow.
