Vasodilation and Vasoconstriction. This is so contradictory?

  1. Nov 8, 2009 #1
    Hello everyone,

    I find this so contradictory so please help to understand this.

    In vasoconstriction,

    1. The flow of blood should increase but this would also mean higher resistance so does the flow increase or not. Normally when we constrict something we expect higher speed don't we.
    2. In vasoconstriction pressure should be higher but again does the resistance decrease the pressure.

    My questions for vasodilations are exactly the same but vise versa.

    Thanks for anyone who is going to help :smile:
