ALDOSTERONE DO
Promotes urinary reabsorbtion of Na+ (sodium)
Increases water reabnsorption vis
Osmosis
Reduces loss of water in urine
KEEPS WATER IN
Atrial natriuretic peptide (ANP)
Promotes secretion of Na+(sodium)
Increases more loss of water in urine
Lets water go!
ANTIDIURETIC HORMONES (ADH)
Uses aquaporins to increase water reabsorption in kidneys
Similar to aldosterone
Reduces loss of water
KEEPS WATER IN

Where is it produced
What does it do
Produced in kidneys
Stimulates RBC precursor cells
Thrompopoietin
Produced in the liver
Stimulates platelet precursor cells
Cytokines
Produced by red bone marrow cells
