If body temperature increases above normal, what occurs?
a. sweat is produced by both eccrine and appocrine glands
b. the nervous system causes blood vessels to dilate
c. sweating occurs and blood vessels of the dermis dilate
d. sweating occurs and the blood vessels of the dermis contract

The answer is C. You will begin to sweat and your blood vessels dilate.

This happens because as you sweat you body temp is rising or becoming hotter, thus the blood vessels Dilate to allow more flow to the organs and tissues. Another way to look at it is if you are cold, the blood vessels will constrict and blood flow is be much slower. This make the blood flow turn to more important or gain and tissue in the body so that they can receive blood first. Because of this turn in blood and construction of the vessels, parts like the fingers on our hands or toes of our feet are first to get cold because they do not get blood priority. :)

Does that make sense? I hope I does.

Good luck :)

The answer is reflection.
