Arteries and veins have different structure. Arteries are thicker and more muscular than veins.
Arteries are responsible for pumping oxygenated blood from the heart to the rest of the body and veins are responsible for returning blood from the body to the heart.
The tunica media of the artery is thick, whereas the tunica media of the vein is thin.
Arteries carry oxygen-rich blood away from the heart and towards the body's tissues, while veins carry oxygen-poor blood from the body's tissues back to the heart.
There are no valves present in arteries, whereas veins contain valves.
Arteries tend to be deeper within the body, and have a more complex branching pattern, while veins, are closer to the surface of the body and have a simpler branching pattern
