<Li> the ACTH stimulation test, which is sometimes used to stimulate the production of aldosterone along with cortisol to determine whether primary or secondary adrenal insufficiency is present . However, ACTH has only a minor role in regulating aldosterone production; with hypopituitarism there is no atrophy of the zona glomerulosa . </Li> <Li> the stretch receptors located in the atria of the heart . If decreased blood pressure is detected, the adrenal gland is stimulated by these stretch receptors to release aldosterone, which increases sodium reabsorption from the urine, sweat, and the gut . This causes increased osmolarity in the extracellular fluid, which will eventually return blood pressure toward normal . </Li> <Li> adrenoglomerulotropin, a lipid factor, obtained from pineal extracts . It selectively stimulates secretion of aldosterone . </Li> <P> The secretion of aldosterone has a diurnal rhythm . </P>

The release of aldosterone is triggered by a decrease in blood plasma potassium levels
