What is vascular resistance?
Vascular resistance describes the degree in which blood vessels of the cardiovascular system - arteries, capillaries and veins - affect blood flow to different organs of the body. The main characteristics that determine the amount of resistance are the diameter and length of the blood vessels and the viscosity or blood thickness. Of these three factors, the most important vascular diameter is.
vasoconstriction, which is a narrowing or narrowing of the diameter of the blood vessels, increases vascular resistance in the same way as the nozzles of hoses and faucets are limited and subsequently increase the pressure flowing through the pipeline or hose. Two types of vascular resistance are systemic vascular resistance and pulmonary vascular resistance.
Pulmonary vascular resistance control concerns blood flow in the lungs. The tension in the vessels that feed all the organs of the body except the lungs is called the systoiness of the microphone. System resistance is sometimes referred to as peripheral vascular resistance.
often referred to as "quiet murderer", hypertension or high blood pressure, affects millions of people around the world. Many of them do not even realize the state until they enter a serious state. High blood pressure is due to an increase in systemic vascular resistance or by increasing the heart expenditure, which is measured by heart rate and blood volume. Increasing blood pressure determines the volume of blood that is pumped and the measure as the blood vessels are.
uncontrolled high blood pressure can lead to many serious conditions such as heart attack, stroke, aneurysms, congestive heart failure and kidney dysfunction. It can also lead to myocardial infarction, loss of vision, memory damage and even death. Most of the time can be successfully treated with a combination of drugs and lifestyle changes.
Health workers use a wide range of drugs to face the effects of increased vascular resistance, which leads to high blood pressure. Some of them include alpha blockers, enzyme inhibitorsFor converting angiotans, beta blockers, diuretics, Rennin inhibitors and vasodilators.
When connected with certain changes, these drugs can often bring blood pressure often acceptable. These changes include the acceptance of a diet that includes less fat, less sodium and more fiber; development of consistent exercise; stop smoking; weight loss; and reducing stress. It is assumed that the effects of hypertension could be significantly reduced, not if removed, by accepting these lifestyle practices at the beginning of life.
