the artery walls must be thick to withold the pressure of the blood coming right from the heart. veins don't need that thick of walls because there is not as much pressure farther away from where the heart is located
Because the blood is pumped directly into arteries so there is more pressure on the arteries. Because the blood is pumped directly into arteries so there is more pressure on the arteries.
Because the pressure in the artery is much higher than the pressure in the vein so the artery has to hold the pressure
Blood in the arteries is under extremely high pressure as its taking oxygenated blood from our heart.Veins take low pressure unoxygenated blood back to our heart.
because arteries have to expand and handle blood pressure
Because they are much higher priority than other veins. They bring blood from the heart and distribute it to the smaller veins.
Extra protection.
The blood in arteries is under pressure, is being pumped by the heart.
it just is thicker than the veins because the red blood cell need lots of room
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.
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.
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.
it is a VEIN <3
the wall of an artery is usuallythicker that the wall of a vein.
Yes. For equivalently sized arteries and veins, arterial walls are significantly thicker.
The aorta has thicker walls as it is an artery not 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 that the vein had thinner walls and a darker color. The artery would have thicker, more muscular walls and a brighter red color.
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.
No the veins are bigger than the artery
in our body there are both, pulmonary artery and pulmonary vein
The muscularis layer of arteries has a thicker layer of smooth muscle.
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 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.
