What does the middle layer of the artery consist 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.
Which layer of the artery wall thickens most in atherosclerosis?
The tunica media is the thickest layer of of an artery
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
What is the structure of an artery?
The walls of arteries are really thick; they consist of three cell layers. The inner layer is smooth, made of epithelial cells. Because of this smooth texture, it allows the blood that comes through it to flow more freely. The next layer is mostly composed of muscle tissue, and the outermost wall consists of flexible connective tissue. This structure of the artery makes it strong and flexible, and easy for it to pump the blood throughout your body.More Information:Similarly to the wider lumened vein, the artery has numerous structural features.Firstly the artery lumen is small. This is so a high pressure is maintained, and so the blood can flow quickly and efficiently to body tissues.Secondly the arteries wall is very thick. This is so the artery can withstand such high pressure from the narrow lumen. The wall is strengthened thanks to collagenfibres.Thirdly the lumen of the artery is surrounded by a layer of cells known as the endothelium. The endothelium is a thin layer and it simply reduces the friction of blood flow. The endothelium can also unfold.In addition the artery contains elastic tissue. The advantage of elastic tissue is that it can stretch and recoil. Recoil means that it can return the width of the lumen to it's original narrow size. The elastic tissue recoils when the heartbeat rests so high pressure is maintained. This can sometimes be observed on the skin when a vessel 'beats'.Furthermore the artery contains smooth muscle that constricts (narrows) as it contracts. This can be useful to improve gas exchange at the alveoli.
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 is a vessel with a thick layer of smooth muscle and elastic fibers that allow for expansion?
An artery is a vessel with a thick medial layer, consisting of smooth muscle to allow for constriction or dilation in order to control blood flow through the vessel.
Is the stratosphere have a thin layer or a thick layer?
thick layer

Artery
What are the properties of an artery?
thick wall , elastic in nature
Thick layer of air that protects earth?
Ozone layer is the thick layer. It protects us from UV rays of the sun.

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 are the differences of the wall of the artery and a vein?
The muscularis layer of arteries has a thicker layer of smooth muscle.
