Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins (called venodilators), large arteries, and smaller arterioles. The process is the opposite of vasoconstriction, which is the narrowing of blood vessels. When blood vessels dilate, the flow of blood is increased due to a decrease in vascular resistance. Therefore, dilation of arterial blood vessels (mainly the arterioles) decreases blood pressure.

An IQ of 123 is in the upper 5% of the population-however, even if you may be blessed with a high IQ, it comes down to what you plan to do to use it to its full capacity. A good IQ test is not age-dependent, so any score over 100 (which is average) would be, by definition, above average, irrespective of age. 2 people found this useful.
Donald Trump is a Genius â But Thatâs Just His IQ! The most well known high IQ society is Mensa. To join Mensa one must score in the top 2% of a standardized IQ test. That really isnât all that outstanding. One out of 50 people have IQs high enough to join Mensa. Numerical IQ scores are not an accurate indicator of intelligence. For instance a score of 72 on the U.S. Navy GCT test is about equal to score of 150 on the WAIS (Wechsler Adult Intelligence Scale). Percentile IQ scores are a more informative measurement. Way back during the 2004 presidential election I wrote an article that shook up the major news networks and the New York Times.
