Vasodilation Is A Natural Process To Lower Blood Pressure And Enhance Blood Flow
However, Capillaries Do Not Increase Blood Flow, Which Can Cause Organ Damage In Eyes And Ears And Even Stroke
Vasodilation is a natural body reaction consisting of the dilation of the blood vessels, occurring when there low oxygen levels in the blood or an increase the body temperature. Increasing the blood vessel diameter results in additional blood flow, promoting oxygen delivery to other parts in the body, that require it. It can be also induced for treating high blood pressure, drug delivery, or oxygen distribution to certain tissues. It can also be caused by exercise, because it delivers additional oxygen and nutrients, to the muscles, alcohol ingestion, which acts as a natural vasodilator, and inflammation, which is the body’s procedure of repairing damage. Vasodilation can be affected by temperature, due to nerve cells that detect high temperature, dissipating it in the skin. Excess weight also affects it, due to that fact that obesity prevents a proper constriction and dilation of blood vessels. Another aspect that affects it is age, because special cells that detect blood pressure begin malfunctioning, leading to high blood pressure in older people. Even though vasodilation is intended to lower blood pressure, it increases pressure on the capillaries, which do not respond to dilation, increasing the risk of organ damage, in eyes and ears, or even a stroke, if these are located in the brain.
