Although arteries and veins share the same basic tunic structure, there are significant differences:
Arteries: The tunica media is thicker in arteries due to a higher content of smooth muscle and elastic fibers, which helps them withstand and regulate the high pressure of blood pumped from the heart. Veins: The tunica adventitia is more developed in veins, providing additional support as veins often operate under lower pressure and may need to accommodate larger volumes of blood.
