Understanding Viruses and Diseases
We are there food. Those germs of the past that best converted our bodies into their own propagation are the germs of the present. Those germs of the present that best convert our bodies into their own propagation will be the germs of the future. Why should we care about the prospects of one particular germ over another? Aren't they all just plain bad? The answer is no. We can never get rid of them all. Their future is our future. If their future goes one way, we will be relatively healthy; if it goes another, we will be sick or even dead. Neglect of the germ's-eye view of the world is not restricted to the average person; it extends to medicine as a whole for most of its history (Ewald 9). Scientists have proven that some viruses are to blame for certain diseases not the genes that have been inherited.
Artherosclerosis is characterized by fatty deposits that develop as streaks inside the lining of arteries and some streaking can be found in teenagers and then by an increasing proportion of the population from then on. If you were to ask the experts what causes arteriosclerosis the answer would depend on the expert. Researchers do not agree on the causation but they have agreed on possible risk factors such as smoking, a high fat diet, high cholesterol levels, high blood pressure, high iron levels, inflammation and bad genes. None of which appear to be the primary cause because if you were to eliminate one possible cause you should eliminate the disease. Many researchers have begun to think that many diseases including cancers originate as a composite of risk factors and that approach does not make sense because it suggests that Human arteries are so fragile that any one or combination of the...

...ing even more slowly is research that would involve a cure or possibly vaccines to the most deadly or most taxing of ailments. If the medical community could stop being so eager to dismiss their colleges research before reviewing all the facts then maybe research could move forward to cures then children would not have to die of cancer anymore or another family would not have to bear the anguish of caring for a family member severe mental illness or disability. Death may never be remedied but suffering may.

I originally thought that diseases were not beneficial to humans at all, due to the negative persona surrounding them. However, the reading changed this, as it explained that inherited diseases were kept in our genepool, being that they served a purpose in the past, or even in the present. Each disease provides insight into how humanity has evolved, in response to the ever changing environment around us. Though these conditions would eventually lead to our downfall, they would leave us better suited towards surviving tomorrow, which ultimately, matters the

Bloodborne Pathogens are pathogenic microorganisms that can eventually cause disease. They are found in human blood and other bodily fluids such as synovial fluid, semen, vaginal secretions, cerebrospinal fluid and any other fluid that mixes or has contact with blood. The bloodborne pathogens are pathogenic, which means they are disease causing, and they are also microorganisms, which means that they are very small so the human eye cannot see them.
Although atherosclerosis affects millions of people around the world, there are many ways to prevent and treat it once it has developed. Simple life style changes can greatly reduce the inflammation and damage to the endothelial wall of the artery. It is very important that people who have high blood pressure or diabetes get regular checkups; if atherosclerosis goes untreated, the adverse effects, such as stroke or myocardial infarction can be deadly.
Coronary artery disease (CAD) is the most common type of multifactorial chronic heart disease. It is a consequence of plaque buildup in coronary arteries. The arterial blood vessels, which begin out smooth and elastic become narrow and rigid, curtailing blood flow resulting in deprived of oxygen and nutrients to the heart [1].
Coronary heart disease is defined by the hardening of the epicardial coronary arteries. The buildup of plaque in the arteries slowly narrows the coronary artery lumen. In order to better understand the physiology of the disease, it is important to first know the basic anatomy of the human heart. The aorta, located in the superior region of the heart, branches off into two main coronary blood vessels, otherwise known as arteries. The arteries are located on the left and right side of the heart and span its surface. They subsequently branch off into smaller arteries which supply oxygen-rich blood to the entire heart (Texas Heart Institute, 2013). Therefore, the narrowing of these arteries due to plaque buildup significantly impairs blood flow throughout the heart.
from the Plague. What is ironic about this is that this pure science tends to benefit humanity more than commercialism science in the long run. The notion that one significant improvement over a long period of time is better than a series of failures and half-successes is drowned out by the propaganda of commercialism. Pure science produces methods and medicines that are certain. They have been thoroughly tested and proved to be successful, as opposed to the medicines produced by commercial scientists.
A pandemic is defined as a disease that has the ability to outbreak and spread globally. A pandemic is determined by how a particular disease spreads rather than how many lives it has claimed. A future pandemic can easily occur if and when a mutation of a new influenza A virus emerges. A pandemic of this type is easily possible to spread quickly and globally due to that when a new strand of the virus emerges, it will be highly unlikely that the human population will have a built up immunity to it.
...in the fields of both science and medicine, future epidemics of any disease can be handled better. When a lethal disease begins to rampage a population, research on similar epidemics can help the world contain, cure, and prevent the disease to protect the world and its population.
Atherosclerosis is the most common cause of CAD. Atherosclerosis is a progressive disease characterized by fat deposits in the arteries causing them to block the normal passage of blood. No one is quite sure how atherosclerosis develops. The plaque consists mostly of cholesterol, phospholipids and smooth muscle cells. They also reduce the size of the lumen of the affected artery which impairs the blood flow of this artery and later on could form a thrombus that will completely occlude the vessel. “Unfortunately, signs and symptoms of atherosclerosis usually don’t develop until at least 70% of an artery’s lumen has become obstructed. Angina is almost always the first symptom to appear.”(Journal: The killer behind CAD,2010). Modifiable factors that could prevent the occurrence of CAD include cigarette smoking, obesity, physical inactivity, atherogenic diet like diet high in cholesterol, use of contraceptive and hormone therapy replacement. “Women continue to ...
Cardiovascular Disease is broad term that encompasses several diseases related to heart or blood vessels or both. Some of which include, congenital heart abnormalities, ischemic heart disease, hypertension, diseases of the cardiac valves, cardiomyopathies, and cancer. There are many causes of CVD but hypertension and atherosclerosis (hardening of the artery) are most common. It’s true when H.L. Menchen said, “As the arteries grow hard, the heart grows soft.”
Being aware is the key to prevent any disease from developing. Because of the medical advancement we have today, the chance of getting infected with and developing diseases has decreased rapidly. However, just because the percentage has been lowered does not mean it is fine to forget about the existence of diseases. Are you aware of how many fatal diseases you can develop? The way you live and act can affect the possibility of you developing a disease, that you can prevent by being careful and consider about how you are living your life. However, the disease you possess in your genes passed down from past generations in your DNA cannot be changed. Another thing to be aware of is that genetic diseases are common to those who come from a general

The arteries supply blood rich in oxygen to the body, the veins direct deoxygenated blood from the capillaries back to the heart. These roles make up the circulatory function. Blood flow through these blood vessels can be disrupted resulting in peripheral vascular diseases. These diseases occur as a result of narrowing or blocking of the blood vessels. The risk factors of peripheral vascular diseases include diabetes, smoking, high level of cholesterol, overweight, high blood pressure etc. these risk factors result to aneurysms, Raynaud’s diseases, Buerger’s disease, renal artery disease etc. With this diseases, the peripheral vascular system should be assessed to enable nurses and other health personnel make good
