What is the structer of an artery?
The walls of the arteries are genrally very thick. The innermost layer is made up of epithgelial cells. The middle layer consist mostley of muscle tissue. The outermost layer is made up of flexible connective tissue. The material allows it to withstand the force of the pumping blood. Got it from the TXT book =D
Which of the layers of an artery wall is regulated by the sympathetic nervous system and many hormones?
the middle layer, tunica media
What is the smooth muscular layer of the renal artery called?
As with all blood vessels, the renal artery has a layer called the tunica media, which is usually rich in vascular smooth muscle.
What artery wall is made of 6 layers?
Arteries actually have 5 layers, it is the veins that have 3. Arteries have: -the Outer coat -Elastic layer -Middle coat (thin) -Another elastic layer -Endothelium
Which layer of the artery wall thickens most in atherosclerosis?
The tunica media is the thickest layer of of an artery

What microscopic vessels composed of simple squamous epithelial cells are called?
Tunica Intima is the innermost layer of the wall of the artery. The wall is consist of simple squamous epithelium which is called endothelium.
What is the stucture of an artery?
The walls of the arteries are very thick in fact artery walls consist of three cell layers.
What are the layers that make up the wall of an artery?
Arteries actually have 5 layers, it is the veins that have 3. Arteries have: -the Outer coat -Elastic layer -Middle coat (thin) -Another elastic layer -Endothelium
What are the layers of the ozone layer?
There is no layer of ozone layer i.e. distinction. It does not consist of any layer, only a single layer is there.
What are the differences of the wall of the artery and a vein?
The muscularis layer of arteries has a thicker layer of smooth muscle.
What is the smooth muscular layer of the renal artery called?
As with all blood vessels, the renal artery has a layer called the tunica media, which is usually rich in vascular smooth muscle.
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.
What makes a vein different from an artery in terms of the structure?
The artery has more muscle, media layer. This is used for contraction. The veins have little muscle layer, but have valves to prevent back flow.
What layer consist of endothelium?
Capillary walls consists of a single layer of flat endothelium
What are the walls of the aorta made of?
The aorta is the largest artery in your body.It is made up of 4 significant sections:Lumen - The gap in which the blood travels away form the heart. In an artery this is smaller than a vein.Tunica intima - This is a thin layer on the innermost section of the artery. It is made up of squamous epithelium cels, allowing the blood to move quickly across them at a high pressure.Tunica media - This is the layer in the middle of the artery. This is the thickest layer of the three. It is mostly made up of smooth muscle fibres and collagen fibres.Tunica externa - This is the outermost layer. It is mostly made up of collagen fibres, though it does have a few smooth muscle fibres.This applies to all arteries, not just the aorta.
