The cross section of an artery typically shows a thicker wall compared to that of a vein, due to the higher pressure of blood flowing through arteries. Arteries have a narrow lumen and three distinct layers: the tunica intima, tunica media (thick muscular layer), and tunica externa. In contrast, veins have a wider lumen, thinner walls, and less muscle, with valves present to prevent backflow of blood. These structural differences reflect their distinct functions in the circulatory system, with arteries transporting oxygenated blood away from the heart and veins returning deoxygenated blood back to it.
