Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.

Is the middle layer thicker in veins or arteries?
arteries.
Why are the larger arteries white?
Because the the outer walls of the bigger arteries are thicker. the thinner the wall the more transparent it is. Because the the outer walls of the bigger arteries are thicker. the thinner the wall the more transparent it is.
Which type of vessel carries blood away from the heart?
Arteries carry blood away from the heart and veins carry blood into the heart.
Which layer of the artery wall thickens most in atherosclerosis?
The tunica media is the thickest layer of of an artery
What do you say that larger lymph vessels are comparable to veins rather than arteries?
Veins have wider lumens than arteries. Veins have thin muscular walls since low pressured blood passes through veins. the walls of the veins however have the same components as in arteries, that is, they have a muscular wall, a connective tissue wall, an endothelium and a layer of elastic tissue. Since arteries experience higher pressured blood the muscular player is much thicker than the one in the veins. therefore, the lumen of the artery is much smaller than that of the vein. Therefore, since lymphatic materials must pass through lymph vessels having the materials being somewhat large, a wider lumen is needed, like that of the veins.
Are the walls in arteries thicker than the walls in veins?
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
What has thinner walls arteries or veins?
Arteries have thicker wall because the pressure in the arteries is much higher.
Contrast the structure of veins and arteries for thickness of muscle and elastic tissue?
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.
Do arteries have the same structure but much thicker walls than veins?
yes
Is the wall of an artery thicker than that of a vein?
Yes. For equivalently sized arteries and veins, arterial walls are significantly thicker.
Are veins thicker than arteries?
The tunica media is thicker in arteries than in veins.
How does the structure of each mayor type of vessel differ from the other type?
The major blood vessels include the Arteries which have thicker walls compare to veins and blood flows in pulse, Veins which have thicker walls compared to capillaries and have vales , and lastly Capillaries which are smaller compared to veins and arteries and do not have valves.
Why are the walls of the arteries thicker than the veins?
i don't knw pls ask your bio teacher in your school.
Why are the walls of arteries relatively thicker than those of the corresponding veins?
In general, the walls of arteries are thicker than those of veins. The tunic media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue. This anatomical difference reflects a functional diffeerence in the 2 types of vessels. Arteries, which are closer to the pumping action of the heart, must be able to expand as an increased volume of blood flows off into the circulation during diastole. Their walls much be sufficiently stong and resilient to withstand such pressure fluctuations. The tunica media is thicker in the arteries mainly for maintaing blood pressure and continuous blood circulation.
Is the middle layer thicker in veins or arteries?
arteries.
Is arteries wall thicker or veins?
artries
How thick are the walls of capillaries compared to those of arteries and veins?
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.
