LDL or bad cholesterol comes from food that is a high source of cholesterol and/or saturated fats. Plaque forms when bad or LDL cholesterol builds up in your bloodstream and attaches to the arterial wall, as more LDL builds up the plaque becomes larger, this can become a major problem for your cardiovascular system. Because plaque is a substance that has rough edges, it reduces the elastic nature of the artery which means your heart will have to work double-time to pump the necessary blood to all your limbs, that will mean your limbs won’t get the amount of oxygen that they require to function properly. Plaque can also narrow the area blood has to pass through, this means your heart has to work overtime and overall capacity of your cardiovascular system is lowered. When the LDL cholesterol embeds itself in the wall of the artery it than damages the artery then blood pressure expands it which causes an aneurysm. When an aneurysm is too weak there is a high possibility of it bursting, when that happens it leaves the cells in and around that area without oxygen. If that artery is connected to a major vital organ the person will most likely die. When the blood flow is slowed it shows a greater risk for blood clots and although blood clots are natural and important to healing broken blood vessels, if blood clots gather inside the blood vessel this proves to be a serious health risk. The clots have the possibility to get stuck and completely cut off the blood flow to cells, leaving them without oxygen and causing them to die. If a clot gets inside a blood vessel connected to a major organ this could cause the person to die. The heart is fed by the coronary artery, if plaque or a blood clot blocks off blood flow to the heart, the heart ...

...tance. Things that may protect you from cancer are; a proper balanced diet and a strong immune system. Your body has a sort of, command center that controls the growth of skin. Sometimes the cell reproduction process goes wrong and the newly created cell is a mutation of the original cell. Most cell mutations do not survive long enough to become harmful but sometimes the genetics of the cell allows it to survive and the cell could become cancerous. Some things that make a cell cancerous are; it not being attached to the command center, when the cell doesn’t give notice to the signal sent to tell it to stop growing, and when the cell gains its own blood vessel network system. Cancerous cells can move around and take over other sections of the body which destroys the person. Cancer and heart disease and many other severe conditions are there for many years before you e
However, exposing the body to high levels of cholesterol results in hypertensions and other cardiovascular disorders. High levels of cholesterol can even lead to atherosclerosis, a disposition of fatty substances, and fibrosis of the inner arteries.
In general, the word cancer is the name given to a collection of related diseases (What is cancer? n.d.. ). In our everyday life multiple thousands of your cells divide in order to keep the function of that certain cell ongoing. Through out all types of cancer, the body begins to force cells to divide without cease which then spreads to the surrounding tissue. Cancer can take form in any part of the human body, were thousands of cells are cancerous. Through time human cells grow and divide to form new ones as it is a requirement for the body to keep functioning. Therefore
CHD is primarily due to atherosclerosis, which is the blockage of blood flow in the arteries due to the accumulation of fats, cholesterol, calcium and other substances found in the blood. Atherosclerosis takes place over many years, but when the blood flow becomes so limited due to the build up of plaque in the arteries, there becomes a serious problem. “When...
Coronary artery disease develops when your coronary arteries the major blood vessels that supply your heart with blood, oxygen and nutrients become damaged or diseased. Cholesterol containing deposits or plaque on your arteries are usually to blame for coronary artery disease. When plaques build up, they narrow your coronary arteries, causing your heart to receive less blood. Eventually, the decreased blood flow may cause chest pain, shortness of breath, or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack.
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.
Cancer is known as one the prevalent diseases in the world today. Every year millions of people are afflicted by this disease. Cancer is a class of diseases wherein cells grow out of control. There may have been no proven way to completely prevent cancer but there are steps that can lower your risk or keep it from recurring. Eating a healthy diet is always on the top of the list when it comes to cancer prevention. Certain components on food are found to help in lowering the risk of cancer, such as antioxidants, phytochemicals, and omega-3 fatty acids. Physical activity may also reduced cancer risk by preventing obesity, reducing hormone levels and inflammation, and improving the immune system.
To prevent new cancers from taking off, scientists look at risk factors and protective agents. Anything that increases your chance of getting cancer is called a cancer risk factor; anything that lessens your chance of getting cancer is called a cancer protective factor. Some risk factors for cancer can be averted, but many cannot. For instance, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Normal excise and a healthy diet can help reduces the chances, but do not promise.
Coronary Heart Disease (CHD) is the leading cause of death in the United States. 13 million people are affected by this disease. CHD is also called Hardening of the Arteries, CAD. CHD is cause by the build-up of plaque in the arteries that connect to the heart. The build-up is caused by fat materials and other substances that form plaque. The plaque builds-up on the wall of the coronary arteries. The coronary arteries are responsible of the blood flow and oxygen that gets to the heart. The build-up of the fat materials causes the arteries to get narrow, this results in the blood flow and oxygen to the heart to slow down or even stop.
Heart disease is caused by plaque buildup in arteries also called atherosclerosis which leads to blockages. The arteries change from smooth and elastic to...
The disease occurs in a person because there is a thickening or blockage of artery walls that occur due to the presence of fat build-up along the walls. The formation of plaque is also known as aterioscelorosis which is usually a result from cholesterol fats, nicotine, high blood pressure and unbalanced blood sugar level. The arterioscelerotic cardiovascular disease is severe and chances of development increases as people aged.
Coronary Artery Disease can be very deadly. It is actually listed as the number 1 killer in America. It is documented that Coronary Artery Disease has affected over 13 million Americans. Coronary Artery Disease can also be known as Heart Disease. CAD happens when plaque builds up in the arteries, resulting in blood flow being blocked. This can have deadly consequences such as strokes and heart attacks. This happens when the walls of the arteries change from being smooth and elastic, to hard and rigid. This restricts the blood flow to the heart. This prevents the heart from getting the oxygen and nutrition it needs to function properly. (Coronary Artery Disease 2014)
What is coronary heart disease (CHD)? It is a disease when plaque gets built up in the coronary arteries; and the job of the arteries are to provide rich-oxygenated blood to the heart muscle. Built plaque in the arteries leads to atherosclerosis and the plaque that is built can result from over the years. Throughout the years, the plaque tends to get hard or can rupture. If hardened, the arteries are now narrow and have weakened the flow of blood that travels to the heart. Blood clots can form from the plaque rupturing which can cause a great chance for the blood flow to be mostly blocked or blocked altogether. There are other names for coronary heart disease such as coronary artery disease, atherosclerosis, ischemic heart disease, etc.
Tortora & Derrickson (2009) further illuminates the distinction between LDL and HDL cholesterols and why these differences incur such conflicting effects in the body. LDLs convey about 75% of the total cholesterol in blood and deliver it throughout the body to cells so that they may repair cell membranes and create steroid hormones and bile salts (p. 991). However, when their number exceeds what is necessary, LDLs leave cholesterol in and around the smooth muscle fibers in arteries (p. 991). Thus, LDLs have earned a “bad” reputation. In contrast, HDLs remove excess cholesterol from body cells and blood and transport it to the liver for subsequent elimination, preventing its accumulation in the blood (p. 991). Thus, their “good” reputation is safe. It is important to remember though that both LDL and HDL cholesterols, as well as triglycerides, are essential in certain amounts, and LDLs and HDLs together make up the total cholesterol level used in the diagnosis of high cholesterol.
Skin Cancer is caused by hereditary factors, overexposure to the sun, and weak immune systems. (“Skin Cancer” infotrac.com) One reason people tend to get skin cancer is when someone in your family has passed their genes down to you, known as hereditary. Normally hereditary is one of the causes in the development of melanoma. For all types of skin cancers, overexposure of the skin to UV radiation in sunlight is the most frequently blamed source of skin cancer. “Research suggests that sunburns received early in one’s childhood can lead to skin cancer later in life” (“Skin Cancer” infotrac.com). For example, when someone gets sunburned, you usually don’t know till ten to twenty years after and that’s why people don’t get skin cancer till they reach their twenties.
When one or several lipids combine with proteins this forms lipoproteins, these transport fat throughout the bloodstream. High-density lipoproteins, also known as HDL, carry fat away from body cells, therefore preventing its growth in the artery walls. Low-Density Lipoproteins, also known as LDL, contain a high amount of cholesterol and seem to help the build up of fatty materials in the artery walls. The situation that you should go for would be high HDL and low LDL levels. Your goal should be to keep your overall cholesterol at below 200, with LDL lower than 40, and your HDL should be at around 160. This will lower the risk of heart disease and other related problems with cholesterol.
