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.
Answer by Bessey52. Confidence votes 7.6K. 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.
First, I say intelligence doesn t make you good or bad or a better person than any other; it gives you some tools and advantages and it gives some problems too. As to that score, It depends on the test in part. The average IQ is 100. Some IQ tests use a Standard Deviation of 15 and some use 16.ikewise, a 50 year old with an 85 IQ probably had an 85 IQ when he was 5 years old. If you scored a 148, you may want to check out Mensa -- an international organization whose membership have an IQ tested in the top 2% of the population. Source(s): www.mensa.org.
