flow = change in pressure /resistance
if resistance is increased flow will decrease
if r is inc, and flow remains the same, pressure will increase

P=Q*R
to maintain P, Flow will decrease. But if flow is kept constant then the pressure upstream from the point of resistance will be increased and the pressure downstream will be decreased. thts my very simple explanation.
lets see wht the others hv to say.

no. "to keep vessels open" itself says that the vessels are tending to collapse.that is high resistance
