Thanks for the clarification - that's what I meant. I'm not sure I can edit the parent post. Salt does have an immediate effect on blood pressure, as you said, because of osmotic effects. Increased salt in the intravascular space will draw water from other areas into the vessels, thus increasing blood pressure. The kidney has both osmotic and pressure sensitivity.
