High Blood Pressure High Blood Pressure is anything that alters in peripheral vascular resistance, heart rate, or stroke volume that affects systematic arterial blood pressure. Long term effect of high blood pressure are serious and can cause heart attacks, strokes, kidney failure, and retinal damage. Hypertension is another medical word that substitutes the meaning of high blood pressure. It is known as the “silent killer” because it does not create any symptoms. The most common reason for high blood pressure is arteriosclerosis. Arteriosclerosis is the thickening and hardening of the walls of the arteries, occurring in old age. Four control systems have a job in maintaining blood pressure. These are the arterial baroreceptor and chemoreceptors’ system, regulation of body fluid volume, the renin- angiotensin system, and vascular autoregulation. Primary hypertension mostly occurs from a defect or malfunction in some or all of these…show more content…
Baroreceptors are sensors in the vascular system that respond to changes in pressure within blood vessels. Baroreceptors are found in the carotid sinus, aorta; the largest artery and the heart’s muscular pumping chamber, and wall of the left ventricle. They monitor the level of arterial pressure and act against in the order to lessen the force in the dilation of blood vessels, which decreases the blood pressure. Chemoreceptors, located in the brain, the two main arteries that carry blood to the head and neck, and aortic body of baroreceptors, are sensitive to changes in concentrations of oxygen, carbon dioxide, and hydrogen ions (Ph) in the blood. A decrease in arterial oxygen concentration or Ph causes a reflexive rise in pressure where an increase in carbon dioxide concentration causes a decrease in blood pressure. Ph is the numeric scale used to identify the basicity and acidity of a solution. Basic is on the top of the scale while acid is on the
