Primary Target tissue is the Kidney. Most important action to↑ Na+ reabsorption by Collecting Ducts
Water is reabsorbed along with the Na+.Considered to control the amount of Na+ Rather than the Concentration of Na+ in the ECF
Promotes the Secretion and Excretion of H+ by the Collecting Duct.
Promotes the Secretion and Excretion of K+ by the Collecting Duct
Affects also seen on the Distal Colon.
Loss of 4 L of intestinal fluid cause ↓Extracellular Fluid (E.C.F.) = ↓ of Cardiac Output (C.O.) = ↓ B.P. = ↓ Renal Blood Flow (R.B.F.)
↓ of R.B.F. activates the renin-angiotensin system = ↑ the Angiotensin II that stimulate the secretion of ALDOSTERONE
↑ Aldosterone = ↑ Reabsorption of Salt (Sodium) and Water by the Kidney.

A 68-year-old man has had worsening dyspnea and orthopnea for the past 3 years with increased production of frothy sputum. On examination, crackles are auscultated at lung bases. A chest radiograph shows bilateral interstitial infiltrates, distinct Kerley B lines, and a prominent left heart border. Laboratory studies show Na+, 135 mmol/L; K+, 3.8 mmol/L; Cl−, 99 mmol/L; CO2, 25 mmol/L; glucose, 76 mg/dL; creatinine, 1.5 mg/dL; and urea nitrogen, 30 mg/dL. Fractional excretion of sodium is less than 1%. Plasma renin, aldosterone, and antidiuretic hormone levels all are increased. Brain-type natriuretic peptide (BNP) is 200 pg/mL (normal
