Properties of the flow disorders of the cardiovascular System
Ang presyon ng dugo ay isa sa mga pangunahing indikasyon ng kalusugan, na hindi lamang sumasalamin sa puso at sistema ng sirkulasyon, kundi pati na rin sa aktibidad ng mga bato, mga organo ng endokrin, paggawa ng dugo, at ng sistema ng nerbiyos. Kaya naman, walang isang unibersal na gamot laban sa mataas na presyon ng dugo. Hindi ka basta basta puwedeng pumunta sa botika at magtanong ng 'tableta para sa presyon,' kasi agad na tatanungin ng parmasyutiko – anong gamot ang nireseta sa iyo ng doktor?

I am happy to offer a scientific Text on the topic of properties of the flow in the case of diseases of the cardiovascular system in English:Characteristics of the flow in the case of diseases of the cardiovascular systemThe dynamics of the blood flow in the human body is a complex physiological phenomenon, which is closely connected with the function of the cardiovascular system. In healthy people, the blood flow is characterized by a laminar flow, in which the blood cells are flowing evenly and parallel to the vessel wall. This type of flow minimizes resistance and allows a more efficient supply the organs with oxygen and nutrients.In various diseases of the cardiovascular system, however, significant changes in the flow characteristics occur. In the Following, the main pathologies and their impact on the flow dynamics are described:1. AtherosclerosisAtherosclerosis leads to narrowing of the blood vessels (stenosis) due to the Plaques, which deposited on the vessel walls. These constrictions disrupt the laminar flow, and can lead to turbulent flows. Turbulence increase the walls of the shear stress on the vessel, which may contribute to the progression of further damage and progression of the disease. The flow velocity in the area of the stenosis increases significantly, while after the constriction decreases — a phenomenon that due to the continuity law (A1⋅v1=A2⋅v2) explained.2. Heart valve defectsDefective heart valves, such as aortic stenosis or mitral regurgitation, the flaps, the flow conditions change within the heart and adjacent vessels. In the case of a stenosis of the aortic valve, the heart has to pump against increased resistance, which leads to an increased velocity of flow through the narrowed valve. This can lead to turbulence and a characteristic Heart murmur (Murmur). In case of Insufficiency, however, there is a back flow (Regurgitation) of blood, which interferes with the normal laminar flow and cardiac output impaired.3. AneurysmsAneurysms are local Outgrowths of blood vessels, leading to an elongation and weakening of the vessel wall. In one aneurysm, the flow pattern changes: It Eddies (Vortices) and areas of low flow velocity form. This promotes thrombus formation, since the blood cells and clotting factors remain longer in contact with the vessel wall. The risk of a thrombus of departure and embolic closure of distant vessels, and this increases significantly.4. HypertensionPersistent high blood pressure (hypertension) leads to structural changes of the blood vessels, including thickening of the vessel wall (hypertrophy of the Media). This reduces the vessel diameter and increased peripheral resistance. The result is an increased flow velocity and an increase in shear stress, which can damage the endothelial cells. In the long term, this favours diseases, the development of arteriosclerosis and other cardiovascular disease.5. Heart failureIn heart failure, the pumping capacity of the heart is reduced, which leads to slow blood flow. A reduced flow velocity increases the risk of thrombus formation, particularly in the chambers of the heart. Moreover, it can lead to a congestion of blood in the veins, which increases the hydrostatic pressure and Edema (water retention) in the tissues caused.SummaryVarious diseases of the cardiovascular system to change the properties of the blood flow in a characteristic way. Turbulence in the case of atherosclerosis via increased speeds with valvular Heart to slow flow in heart failure — these changes are not only symptoms, but often even to the progression of the disease. A deeper understanding of the flow dynamics in cardiovascular pathologies is thus essential for the diagnosis, treatment and prevention of these diseases.If you wish, I can make certain sections in more detail, or other aspects add!
Properties of the flow disorders of the cardiovascular System. A sedentary lifestyle, alcohol, and cigarette consumption increase body weight which in turn hinders healthy blood circulation and strength of arteries and veins. This results in high blood pressure. So, if you’re overweight, you need to monitor your blood pressure frequently.

Hypertension: The silent dangerHigh blood pressure, scientifically as hypertension referred to, is rightly considered to be one of the greatest health challenges of our time. He is one of the main causes for cardiovascular diseases, strokes, and kidney damage — and the Worrying thing is: he Often runs over a number of years completely asymptomatic. That is why it is also called the silence of death.What exactly is hypertension? Blood pressure is the force of the blood against the walls of the blood vessels pushes. A normal value is around 120/80 mmHg. The value is consistently above 140/90 mmHg, it is called hypertension. This Congestion of the vessels and of the heart can lead over time to serious damage.Who belongs to the risk group?Among the main risk factors:Obesity and lack of physical activity,a salt-rich diet,chronic Stress,Alcohol and nicotine consumption,genetic predisposition,Age (the risk increases with age).Why is early detection so important?Because high blood pressure often causes no noticeable symptoms, it remains, unfortunately, often go undetected, until it comes to an acute health emergency. Regular blood pressure measurements at the doctor or at home can be a life-saver. Especially people over 40 years old should keep your blood pressure in the eye.What can you do?Dieuch in an increased value of many of the actions are available:Style changes: More to life exercise, healthy diet with reduced Salt intake, weight loss.Stress management: relaxation techniques such as Yoga or Meditation.Medications: If necessary, the doctor blood-rubs-pressure-lowering drugs to reduce the risk of complications significantly.High blood pressure is not an inevitable Fate. With a conscious management of their own health, regular checkups and, where appropriate, early treatment of this silent danger to be successful in chess to keep. The message is clear: pay Attention to your blood pressure — it is an important indicator of your General well-being and life expectancy.
