Explanation:
Detailed explanation-1: -Arteries have thick walls composed of three distinct layers (tunica) Veins have thin walls but typically have wider lumen (lumen size may vary depending on specific artery or vein)
Detailed explanation-2: -Veins carry unoxygenated blood towards the heart, away from tissues at low pressure so the lumen is large.
Detailed explanation-3: -The great vessels of your heart have a wider lumen (opening) compared with your other arteries and veins.
Detailed explanation-4: -Arteries are more muscular and have smaller, rounder lumens (internal spaces) than veins. The artery lumen has a wavy endothelium, or inner lining, due to the configuration of elastic tissue beneath it.
