Arteries are blood vessels that transport blood, nutrients and OXYGEN to the body. All these substances have to get transported which is why they have more pressure to be forced to different body parts. Oxygen for example contains a lot of pressure. This supports the reason of the walls to be thick so that all the pressure does not cut or damage the arteries!

Why do arteries function better with thick walls?
Blood vessels that take blood away from the heart are called arteries. The high pressure of the blood pushes strongly on the thick, elastic artery walls. They stretch and shrink as the blood moves through them. This movement of artery walls makes a pulse. When an artery passes close to the skin the pulse can be felt and therefore used to count how fast the heart is beating.
What is the thickness of an artery's walls?
It all depends on which one you are comparing, because they come in large ones like the Aorta, down to tiny ones called arterioles. In any case, they are thicker than their corresponding vein.
How have arteries adapted to carry blood away from the heart?
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
Is the walls of a artery thicker than a vein?
Veins have thin walls because blood that flows through them is usually low in pressure while the blood that flows through the arteries are usually of high pressure. The walls are thick to prevent bursting.
What is the stretching of artery walls?
An Aneurism.
What has thick muscular walls?
Artery
What is the stucture of an artery?
The walls of the arteries are very thick in fact artery walls consist of three cell layers.
Describe the structure of a capillary wall?

Why are the walls of arteries proportionately thicker than those of the corrosponding veins?
Artery walls need to be thick because they have to cope with high pressures produced by the cardiac cycle, the arterys are made thick by cardiac muscle.
What is the wall of a artery called?
Walls of arteries are made up of different cells, muscle, and connective tissue and is very thick. The walls have to be thick because the pressure from the blood is so great that without the thickness, the walls would easily rupture, which would be fatal.
What type of vessel holds the greatest volume of blood?
Veins, but there walls aren't that thick.
