1- arteries have a thicker tunica media ( i.e. smooth muscle layer) baing pulsatile while veins being non-pulsatile do need smooth muscles in their wall just to maintain the tone or to adjust the size of lumen.
2- thinner walls of veins with more elasticity give them more compliance and thus they can store more blood serving the function of blood reservoirs.
N.B. exchange of nutrients, gases and fluids occurs only in capillaries thus it has nothing to do with the thickness of arterial or venous walls.
What else can I help you with?
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 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 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.
Is Artery more thicker than vein?
the wall of an artery is usuallythicker that the wall of a vein.
What is the differences in blood in the femoral artery and femoral vein?
The blood in the femoral artery is oxygenated and rich in nutrients, as it carries blood away from the heart to supply the lower limbs. In contrast, the blood in the femoral vein is deoxygenated and contains waste products, as it returns blood from the lower limbs back to the heart. Additionally, the femoral artery has thicker, more muscular walls to withstand higher pressure, while the femoral vein has thinner walls and valves to help prevent backflow.
Is the wall of an artery thicker than that of a vein?
Yes. For equivalently sized arteries and veins, arterial walls are significantly thicker.
Is the artery bigger than a vein?
No the veins are bigger than the artery
Why pulmonary is an artery rather than vein?
in our body there are both, pulmonary artery and pulmonary vein
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.
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.
