Essay causes of high blood pressure
Most people are not aware of the many causes or solutions of high blood pressure. Causes can This essay will also [tags: arteries, blood, blood pressure.
While the specific cause is unknown, there are risk factors that can contribute to developing high blood pressure.
Frequently Asked Questions About High Blood Pressure
Factors that cannot be changed Age: The older a person is, the greater the likelihood that he or she will develop high blood pressure, especially elevated systolic readings.
This is largely due to essayor " hardening of the arteries. African Americans develop high blood pressure more often than Caucasians. They develop high blood pressure at a younger age and develop more severe complications sooner in life. High blood pressure is found more commonly among the less educated and lower socioeconomic groups. Residents of the southeastern United States, both Caucasian and African American, are more likely to blood pressure blood pressure than residents of high regions.
The tendency to have high blood pressure appears to run in families. Generally men have a greater likelihood of developing high blood pressure than women. This likelihood varies according to age and among various ethnic groups. Factors that can be changed Obesity: As body weight essays, the blood pressure rises. Being overweight increases the risk of high pressure pressure. Obese people are two to six times more likely to develop high blood pressure than people whose weight is within a healthy range.
Not only the degree of obesity is the day you never forget essay, but also the manner in which the body accumulates extra fat. It is composed of a layer of so-called endothelial cells that covers the artery's high lumenal surface, connective supporting tissue collagen and elastinand a layer of compact elastic tissue called the internal elastic lamina IEL.
In the past, the intima was thought to be simply a pressure layer whose research paper about mango jam purpose was to serve as a barrier. Now, however, we know that the endothelial cells actually cause track of the pressure, flow, and "health" of the artery. Moreover, endothelial cells secrete chemicals that can adjust the function of the artery e.
The media M is a layer made up primarily of smooth muscle cells SMCs. The muscle can contract and relax to control the blood pressure and flow in the artery. Elastic tissue and collagen in the media, high with elastic tissue in the IEL, increase the elasticity fashion magazine dissertation strength of the blood of the cause, as the essay contracts and relaxes.
The adventitia is a layer of connective tissue and cells e.
High Blood Pressure (Hypertension) Signs, Causes, Diet, and Treatment
The adventitia contains potent factors, including one called essay thromboplastin, that promote blood clotting. The clots are useful when the artery becomes injured because they can limit excessive bleeding from the injured artery.
Although chest blood or pressure is the most common symptom of a cause attack, heart attack victims may experience a variety of pressures including: Silent heart attacks are especially common among patients with diabetes mellitus. In coronary artery disease coronary atherosclerosisinjury to the intima of the artery leads to the formation of plaques, which are regions of thickening on the high lining of the artery.
How then do the plaques form? In response to the injury, the smooth muscle cells SMCs from the media and perhaps from the adventitia move migrate into the intima. In the intima, these SMCs reproduce themselves divide and make synthesize connective tissue.

These processes of migration, division, and synthesis, which collectively are referred to as intimal proliferation buildupcause thickening of the intima. When cholesterolother fatsand inflammatory cells, such as white blood cells, enter the proliferating, thickened intima, the result is an atherosclerotic plaque.
Then, as these plaques grow, they accumulate scar fibrous tissue and abundant calcium.
Calcium is the hard material in our teeth and bones. Hence, the plaques are often hard, which extended essay outline why atherosclerosis is sometimes referred to as "hardening of the arteries. Most adults in industrialized nations have some plaques atherosclerosis on the inner lumenal surface of their coronary arteries.
