What is the cross section of arteries and 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.
Which bleeds more artery or 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.
How much more pressure does an artery have than a vein?
4
Is it more dangerous to cut a vein or artery and why?
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.
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.
Why are artery walls thicker than vein?
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 what?
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.
Is the wall of an artery thicker than that of a vein?
Yes. For equivalently sized arteries and veins, arterial walls are significantly thicker.
What is the cross section of arteries and 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.
Does vena cava or aorta have thicker walls?
The aorta has thicker walls as it is an artery not vein.
Why the artery has a thick layer muscle then vein?
Because there is more pressure on the artery wall (from the heart) than that of the vein.
Which bleeds more artery or 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.
When empty an artery is more likely to be collapsed than a vein?
No. A vein is more likely to collapse.
How much more pressure does an artery have than a vein?
4
Is the wall for an artery more elastic than the wall of a vein?
Yes
Is it more dangerous to cut a vein or artery and why?
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.
Is the artery bigger than a vein?
No the veins are bigger than the artery
