Relative to the walls of arteries, the veins' walls are thinner, because the pressure of the blood in the veins is much lower; so low in fact, that valves are required to prevent blood in the veins flowing backwards.

Which blood vessel have thin walls and contain valves?
Veins
What thin walls connects arteries and veins?
Arteries enter arterioles enter capillaries enter venules enter veins.
What is one of the two thin walls chambers that receive blood into the heart from the veins?
Atrium
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.
What are some similarities between capillaries and veins?
arteries take blood away from heart. veins take blood to the heart. capillaries have thin walls
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.
Why do capillaries permit the diffusion of materials whereas arteries and veins do not?
why do capillaries permit the diffusion of materials, whereas arteries and veins do not? Because the capillaries are the only blood vessels whose walls are thin enough to permit exchanges between the blood and the surrounding interstitial fluid
What is the term for a thin-walled blood vessel with valves that carries blood to the heart?
Veins are thin-walled blood vessels that carry blood to the heart. The valves in veins help prevent backflow. In contrast, arteries have thicker walls and no valves. They carry blood away from the heart.
One-way valves are found in which blood vessels?
Veins. Veins are blood vessels that carry blood from tissues and organs back to the heart; they have thin walls and one-way valves.
What is the difference between artiries capillaries and veins?
In the body, veins deliver blood back to the necessary organs. Arteries take blood away from the heart so it can be filtered and distributed to the body. Capillaries are thin walls that exist where arteries become veins and vice versa.
What are thick walled blood vessels called?
No. Arteries, which carry blood away from the heart are usually thick walled and round shaped. Veins on the other hand carry blood to the heart and are slightly more thin walled and more elliptical in shape. Capillaries are the smallest of blood vessels and very thin walled. They carry small amounts of blood relative to veins and arteries.
Why are capillaries and not arteries or veins found in alveoli nephrons and villi?
vessel walls must be thin to allow ease to transfer of molecules to these tissues i had this on a test and i got it right :)
