Why are the walls of arteries relatively thicker than those of the corresponding veins?

Answer 1

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.

Answer 2

In general the walls of arteries are thicker than those of veins. The tunica media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue.

Arteries are closer to the pumping action of the heart, must be able to expand as an increased volume of blood is propelled into them during systole and then recoiled passively as the blood flows off into the circulation during diastole

Answer 3

The walls of the arteries are much thicker than the walls of the corresponding veins. The arteries have thicker walls due to the arteries taking the direct pressure of blood from the pumping heart.

Answer 4

More pressure in the Arterial walls than in the veins. If struck, your heart could pump blood over 10 feet. With veins if you get a cut, it just slowly bleeds

The walls of the arteries are found to be thicker than that of a vein because the blood that is carried from the heart to the capillaries has more high pressure. Arteries need thicker walls to prevent the arteries from collapsing. As the blood flowing through the veins does nat have ass much pressure as in that of the arteries their walls are thinner as compared to artery walls.

Answer 5

The walls of arteries are thicker than those of veins so as to keep the pressure of the blood constant while the arteries are constricting or relaxing. Also, the blood pressure in arteries is higher than that in veins, so the walls are thicker to handle the added pressure.

Answer 6

The pressure of the blood flowing through arteries is much higher than veins, so they must be thicker. The arteries are very muscular to maintain good blood pressure.

Answer 7

They have to be that way to accommodate the beating of the heart. This results in pressure being exerted against the arterial walls, and they need to be stronger to deal with that pressure.
