in general no.

Actually yes they are. You have to keep in mind to compare same-action veins with same-action arteries. You could easily compare a vein in the foot to an artery near the heart and the artery will obviously be larger. However compare a vein near the heart to an artery near the heart and the vein is actually larger in circumference.
By thickness an Artery is technically larger because it has to have thicker walls in order to transport oxygenated blood at a high pressure. Veins have thinner walls(they transport the same amount of blood but at lower pressures than arteries) but are actually slightly larger than arteries in circumference.
If you were to think of them like pipes, they would be ranked from largest to smallest as:
-Vein(smaller veins are known as venules.)
-Artery(smaller arteries are known as arterioles.)
-Capillary(smallest of ALL blood transporting tubules.)
Keep in mind Veins transport un-oxygenated blood back to the lungs for re-oxygenation while arteries carry oxygenated blood to the vital organs. Capillaries are like little side streets that help feed blood to the necessary parts of your body that aren't on the main highways.
Varicose or Spider-veins are actually not veins but Capillaries that have risen up to the surface of the skin and often broken due to either trauma or pressure.

∙ 11y agoVeins are smaller than arteries because arteries need to withstand pressure. Capillaries are about half the size as veins.

∙ 11y agoThere are no muscle fibers in blood vessel, so, no this is not true.

Veins consists of fewer elastic and muscle fibers therefore they are more distensible.

Which is larger retinal arteries or retinal veins?
Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.
What are the histological differences between artery and vein?
The tunica media of arteries is larger than that of veins of same size.The tunica adventitia is larger in veins than arteries of same size.
Do the larger arteries contain valves to prevent the back flow of blood?
No, veins have the valves, arteries don't.
What is the amount of muscle in veins and arteries?
The amount of muscle in veins and arteries varies in the sense that arteries are more muscular than veins to give them extra elasticity and strength to deal with surges of blood.
Is it true that the pulse can be felt on arteries but not on veins?
Yes, it's true. The beating of the heart only drives blood in the arteries. As the blood passes from the arteries to the capillaries and then to the veins, it ceases to be pumped by the heart, so no pulse can be felt. Blood in the veins returns to the heart because of the valves in the veins, and because of general muscular contractions in the body, rather than because of the heart.

The tunica media of arteries is larger than that of veins of same size.The tunica adventitia is larger in veins than arteries of same size.
Why the larger arteries appear to be white rather than red but the larger veins are blue?
Not sure about the white arteries but the blue is non oxygenated blood.
Artery and vain 15 differences?
Arteries and veins both carry blood. Arteries are larger and carry blood away from the heart. Veins carry blood to the heart, and they are generally smaller than arteries.
Are veins thicker than arteries?
The tunica media is thicker in arteries than in veins.
What is the characteristic of the veins?
Veins have thinner walls compared to arteries. They also have larger lumens than arteries which is the space inside the vessel. Lastly they have one-way valves to help keep the blood flowing in one direction.
Do the larger arteries contain valves to prevent the back flow of blood?
No, veins have the valves, arteries don't.
What is the blood vessel connecting capillaries to arteries?
Venules, they are smaller and thinner than veins.
Why do you say the larger lymph vessels are comparable to the veins rather than arteries?

Where is the pushing force of the heart greater in arteries or in the veins?
The pushing force of the heart is greater in arteries than in veins. The arteries are closer to the heart itself.
Is it true that the pulse can be felt on arteries but not on veins?
Yes, it's true. The beating of the heart only drives blood in the arteries. As the blood passes from the arteries to the capillaries and then to the veins, it ceases to be pumped by the heart, so no pulse can be felt.
