No, arteries have thicker walls because blood pumps through the arteries around the body, therefore blood pumps through arteries which a high pressure so thick walls are needed. Blood goes through veins with a lower pressure as they lead back to the heart to be oxygenated.
No. They have smooth muscle but no elastic fibers. Their smooth muscle is less than arteries. Elastic fibers provide recoil which is what you need in arteries to propel the blood forward. Veins lack these which is why large amounts of blood can be stored in them without the walls providing any sort of recoil and keeping pressure low.
Yes, but not as much as the wall of arteries.
Arteries have the most thick and elastic walls causing them to have a smaller lumen. They have the most thick walls because they have to withstand the high amounts of pressure as they carry oxygenated blood. This is the reason they have no valves as their is no chance of back flow of blood unlike veins.
artery walls have more elastic tissue and smooth muscle than veins,
elastic tissue
arteries thick walled and elastic blood vessels capillaries and veins
The more pressure it uses, the thicker the walls will be. Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.

Arteries have thick elastic walls that can expand and contract, because they carry blood pumped from the heart. Veins return the blood to the heart but the pressure is not the same as in the arteries.
Arteries and veins have much thicker walls compared to capillaries. The largest arteries and veins have walls up to 5 mm thick, while capillaries have walls that are only one cell layer thick.
The heart pumps the blood out in high pressure so the artery walls are strong and elastic,the walls are thick and contains thick layers of muscle to make them strong , and elastic fibres to allow them to stretch and spring back
this happens because of the vien build up structure in order for the blood to pump the thick blood... now go get your since text book class.... as the bell rang joise and the girls were stil taking about the incident that happen to Johan.
Arterial walls contain thick, muscular tissue to pump blood throughout the body. Veins have thinner walls.
Blood vessels have thick elastic muscular walls, especially arteries, because they have to resist the pressures of having blood pumped through them, and they have to undergo vasodilation and vasoconstriction.
