Why do blood vessels constrict sympathetic?

In blood vessels, sympathetic activation constricts arteries and arterioles (resistance vessels), which increases vascular resistance and decreases distal blood flow. When this occurs throught the body, the increased vascular resistance causes arterial pressure to increase.

What is the point of vasodilation?

The purpose of vasodilation is to increase blood flow to the tissues in the body. In response to a need for oxygen or nutrients, tissues can release endogenous vasodilators. The result is a decrease in vascular resistance and an increase in capillary perfusion.
