Homework Help: biology

Posted by Anonymous on Tuesday, January 25, 2011 at 2:03pm.

I'm doing a paper on a case study. The man, John Doe, is 55 years old, has high cholesterol, and has experienced frequent chest pains, profuse sweating, dizziness, and shallow breathing.

These are the questions I have to answer:
1) What physiological response helped John survive his heart attack?
2) What role did the immune system play, if any? and
3) How has John's blood flow been affected by his heart attack? please I neede help because I am in the hospital thank you.

From cholesterol heart attack dot com

Physiological response:

"John survived because he grew collateral coronary arteries. The coronary arteries supply the heart muscle with oxygenated blood. Chronic high cholesterol results in plaque accumulating inside the coronary arteries. This plaque reduces blood flow to heart muscle. If given enough time, the hearts response to this is to grow collateral arteries. In other words, the arteries branch off so the heart muscle can receive more blood flow. So when John has a heart attack, (an artery becomes occluded from plaque rupture and clot formation) these collateral arteries help supply blood flow to the area of the heart attack. It will not prevent tissue death, but it will keep a significant portion of the tissue that may have died alive.

This is also a significant reason why heart attacks of men in their early 40′s are fatal, and why many heart attacks of men significantly older are not. Younger men have not had time to grow collateral coronary arteries."

About what I posted above.

You probably have this already. This was a response to the exact question you posted here and there.

I did a google search with your question and it directed me to your? other post on that website.

I didn't realize this until after I posted above. I went back to see if I could find any more info for you at that site.

Good luck.
