the wall of an artery is usuallythicker that the wall of a vein.
A cross section of a vein shows a thinner wall than that of the artery, and shows one-way valves. A cross section of an artery shows a thicker, more muscular wall and no valves.
Yes, because there is more pressure in the artery than in the vein so the artery has to be big enough to hold the pressure that's inside it.

An artery because blood is pumped through the arteries at a much higher pressure than the veins. Therefore if you cut an artery you will lose a lot more blood a lot quicker than if you cut 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.
Because the blood flowing through them is at a much higher pressure, therefore they need to be thicker to withstand more pressure.
In comparing a parallel artery and vein, you would find that the vein had thinner walls and a darker color. The artery would have thicker, more muscular walls and a brighter red color.
Yes. For equivalently sized arteries and veins, arterial walls are significantly thicker.
A cross section of a vein shows a thinner wall than that of the artery, and shows one-way valves. A cross section of an artery shows a thicker, more muscular wall and no valves.
The aorta has thicker walls as it is an artery not vein.
Because there is more pressure on the artery wall (from the heart) than that of the vein.
Yes, because there is more pressure in the artery than in the vein so the artery has to be big enough to hold the pressure that's inside it.
No. A vein is more likely to collapse.

No the veins are bigger than the artery
