Homework Help: problem!

Posted by robert on Saturday, August 5, 2006 at 1:01pm.

Atherosclerosis is a condition also called "hardening of the arteries", resulting in reduced elasticity of the arteries. Identify two circulatory problems that might arise from this effect on the vessels.

I have no idea


Atherosclerosis causes two main problems. First, the atheromatous plaques, though long compensated for by artery enlargement, eventually lead to plaque ruptures and stenosis (narrowing) of the artery and, therefore, an insufficient blood supply to the organ it feeds. Alternatively, if the compensating artery enlargement process is excessive, then a net aneurysm results.

These complications are chronic, slowly progressing and cumulative. Most commonly, soft plaque suddenly ruptures (see vulnerable plaque), causing the formation of a blood clot (thrombus) that will rapidly slow or stop blood flow, e.g. 5 minutes, leading to death of the tissues fed by the artery. This catastrophic event is called an infarction. One of the most common recognized scenarios is called coronary thrombosis of a coronary artery causing myocardial infarction (a heart attack). Another common scenario in very advanced disease is claudication from insufficient blood supply to the legs, typically due to a combination of both stenosis and aneurysmal segments narrowed with clots. Kidney, intestinal and other arteries are also typically involved.

cite your sources. Thanks.


Agreed. I don't mind copying and pasting as long as the citations are clear.


I am no medical doctor; however, as I understand it, atherosclerosis is the formation of plaque on the inner walls of the blood vessels. Arteriosclerosis is commonly called hardening of the arteries. That is what my cardiologist has explained to me.


DrBob222-

It was not intentional. It was an oversight. There is a wealth of information on the internet- I found information on the question on at least five sites. I was just trying to help someone out. Researched it, found it and posted it... Sorry for not citing the source. No harm intended.


Jerry,
It was not I but Bob Pursley who referenced your "no references." However, his point is well taken. Your research was accurate. Thanks for helping out.
