Estradiol
Glucocoicoids
Mineralocoicoids
Aldosterone is majorly regulated by K+ & plasma volume The following factors play essential roles in aldosterone regulation: 1. | K+ concentration in ECF - | Aldosterone 2. | Angiotensin concentration in ECF - | Aldosterone3. | Na++ in ECF - decreases aldosterone very slightly4. ACTH from anterior pituitary - necessary for aldosterone sec but has little effect on controlling the rate of secretion in most physiological conditions. ACTH appears to play a permissive role in regulation of aldosterone of these, K+ ion conc. & RAAS are the most potent in regulating aldosterone secretion.
