What changes in blood volume and pressure would be expected as a result of aldosterone deficiency?
Answer: Decreased volume and decreased pressure.
I got this answer right BUT the answer tells me two reasons for the answer. I used the first reason. This is the second and I would like help understanding it, please.
"Because H2O passively follows Na+ during reabsorption in the kidney, less Na+ would result in less H2O reabsorption into the blood stream. This would decrease blood volume."
Thanks. If this isn't clear, I can add more of the answer so please just mention.
Specific question: Why does H2O follow sodium during reabsorption? Is this a general rule of thumb or only in response to aldosterone?
