Aldosterone nefrone

WebMar 1, 2002 · Aldosterone, acting as a mineralocorticoid, is the final endocrine signal in the renin-angiotensin-aldosterone system that targets epithelia in the kidney and colon to regulate Na + (re)absorption and K + secretion. Water ultimately follows the movement of Na + via osmosis, establishing chronic blood volume and thus blood pressure. WebAldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Deoxycorticosterone is another important member of …
