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.
