Aldosterone is sensitive to a few different things. The main thing it is sensitive to is the kidneys.
Distal convoluted tubule
Aldosterone will cause Na+ to be absorbed from a filtrate
Aldosterone promotes water retention and reduces urine volume
Aldosterone helps to indirectly regulate blood levels. A low sodium diet is a way to increase aldosterone in the body.
It decreases the affect of aldosterone secretion.
Aldosterone is a hormone, so it gets to the kidneys via the blood stream.
Aldosterone causes sodium to be retained and potassium to be excreted and blood pressure to rise.

Aldosterone is regulated by negative feedback system except in cases of dehydration in which high sodium levels stimulate more production of aldosterone. Normally negative feedback regulates production.
The higher the aldosterone levels, the more sodium that is reclaimed and the more potassium that is lost.
Aldosterone is a mineralocoricoid hormone secreted by the adrenal cortex.
