When blood vessels in the skin dilate, what is the expected result?

When blood vessels in the skin dilate, a physiological process known as vasodilation occurs, primarily as a response to an increase in body temperature or during exercise. This dilation allows for increased blood flow to the skin, which facilitates the dissipation of heat. The enhanced blood flow makes it easier for heat to be radiated away from the body, thus promoting heat loss.

As the blood vessels expand, the overall resistance in the circulatory system decreases, which can lead to a drop in blood pressure. Consequently, while the heart rate may increase to compensate for the drop in blood pressure, the primary immediate effect of vasodilation is the promotion of heat loss. Therefore, the expected result of blood vessels dilating in the skin is indeed more heat loss and a potential reduction in blood pressure.
