Compare and contrast the structure of arteries with the structure of the veins?

 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) Capillaries are very small and will not be easily detected under the same magnification as arteries and veins.

Explanation: Located throughout the body, arteries transport nutrient-rich, oxygenated blood to organs and tissues. 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.
