Blood vessels are composed of three layers of tissue: tunica externa, tunica media, and tunica interna. The middle layer, tunica media, is composed of smooth muscle and is thickest in arteries because they need to accommodate the higher pressures created by the heart's pumping action which distributes blood throughout the body.

Which layer of the artery wall thickens most in atherosclerosis?
The tunica media is the thickest layer of of an artery
What are the thickest walled vessels?
The thickest walled vessels are arteries, as they have to endure a more forceful power, as the heart, pumps the blood with great force around the body.
Why do arteries have thicker walls then veins?
Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.
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 heart chamber has the thickest walls?
The left ventricle, it works the hardest and needs the most muscle mass.
Which is the thickest chamber of a frog?
the ventricle walls are thickest
Which tunic is especially thick in elastic arteries?
Arterial walls are made up of three layers: the tunica intima, tunica media, and tunica externa. The tunica media is the thickest layer in arteries.
Which layer of the artery wall thickens most in atherosclerosis?

What has the thickest tunica media?
large arteries
Where does the apostrophe go in 'the arteries walls'?
The arteries' walls.
What blood vessels have thick walls?
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.
Which chamber of the heart has the thickest walls?
Left ventricle has thickest walls and has the harder job of pumping blood to the entire body.
What are the thickest walled vessels?
The thickest walled vessels are arteries, as they have to endure a more forceful power, as the heart, pumps the blood with great force around the body.
Why do arteries have thicker walls then veins?
Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.
What has thinner walls arteries or veins?
Arteries have thicker wall because the pressure in the arteries is much higher.
Give a reason why the blood vessel has the thickest and most elastic wall?
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.
What arteriomalacia means?
Is the abnormal softening of the walls of an artery or arteries
