Why does vasoconstriction lead to better blood flow?

Question

I keep reading, as a science student, that when blood flow or pressure goes down, arterioles constrict in order to raise blood pressure. But vasoconstriction actually increases resistance, thereby depriving the tissue further of blood flow.

So what is it that I’m not understanding?

You ever put your thumb in a hose while it’s on? I think that may have something to do with it.
