One difference between an MA and MS degree that some students donât think of is whether the degree is a terminal one. A terminal degree is the highest type of degree that an individual can receive in his or her field. An MA is usually a terminal degree, while an MS degree prepares students for working on their doctoral degrees later.
Aldosterone secretion is controlled by the RAA system and by concentrations of K+ in the circulation, which if increased evokes secretion of aldosterone.
From Wikipedia, the free encyclopedia. Aldosterone is a steroid hormone (mineralocorticoid family) produced by the outer section (zona glomerulosa) of the adrenal cortex in the adrenal gland. (The increased potassium level works to regulate aldosterone synthesis by depolarizing the cells in the zona glomerulosa, which opens the voltage-dependent calcium channels .) The level of angiotensin II is regulated by angiotensin I, which is in turn regulated by renin, a hormone secreted in the kidneys.
