Cardiovascular System Analysis

The cardiovascular system is composed of three organs. Those organs include the Heart, Arteries, and the Veins. The cardiovascular system transports blood, gases, and waste products throughout the body. It also maintains blood pressure fluid, electrolyte, and pH balance. Without the cardiovascular system our body would not be able to function and it would shut down. If our heart stopped, the blood would stop pumping and there would be no oxygen going to our brain. At this point all of the other organs in our body would then shut down.

There are three different layers in the heart. There is the epicardium, myocardium, and endocardium. The first layer, which is the epicardium, is the serous membrane on the outer surface of the heart. The middle

layer, myocardium, is the thick middle layer of cardiac muscle tissue. The third layer of the heart wall is the endocardium, which is the inner lining of the heart chambers and valves; continuous with the endothelium of the blood vessels.
The walls of the vessels consist of the tunica interna, tunica media, and the tunica externa.

The tunica interna, which is the inner layer of endothelium consists of areolar tissue. The middle layer, which is called the tunica media, contains smooth muscle tissue and areolar tissue. The outer layer called tunica externa consists of areolar tissue.

The main purpose of this article was to take patients without established Coronary Heart Disease and reveal the risk equivalents that they could have in the future. I believe the author’s purpose was to inform patients who are on the boarder of Coronary Heart Disease that they are at risk of developing major problems in the future. If they were not going to try and prevent this disease then it will lead to more serious health problems and maybe even death. I believe that they author did make his purpose very clear throughout the paper.

They started off by choosing patients at random and conducting health examinations on each of them. This exam consisted of lab tests and like every other doctors office that I go to for the first time a questionnaire on different types of illnesses that they may have had in the past. After conduction all those tests then they went deeper and the patients had a coronary artery angiography, an ultrasonography, and an oral glucose tolerance test. When the results came back from all the tests, they excluded those patients who had more then one

disease.
I chose this topic for many reasons. The cardiovascular system is the most important system in our body. It contains arteries, veins, and the heart. Without the heart, no one would be able to talk, walk, breathe, eat because we would be dead. The heart is very interesting to me because it pumps blood throughout our entire body. It has such an important role. It amazes me that this little fist sized organ keeps us alive everyday. I also chose this system because my boyfriend has heart problems and every time he goes to the doctor they cant find anything wrong with him. I wanted to learn more and try and figure out why he has theses heart problems and why no one can figure out what is wrong with him. Learning more about the cardiovascular system helps me have a better understanding on how the body functions. Now, I can use the information learned about coronary heart disease and help diagnose patients.
