Answer #1

When plasma osmolality drops, aldosterone is secreted from the juxta glomerulosa cells of adrenal cortex.
Aldosterone acts on the renal tubules (distal tubules and collecting duct) and causes increased absorption of sodium and excretion of potassium. This causes sodium retention. This mechanism helps maintain the plasma osmolality, blood pressure and volume.
Answer : In response to abnormally low plasma osmolality (solute concentration), aldosterone will be produced through the JG comlex and (a) increase sodium reabsorption along with the renal tubules.

1. You have just admitted Mary Roberts, a 70-year-old woman, to the hospital for GI bleeding. Her blood pressure is 130/80, pulse 80/min and irregular, respirations 18/min, and temperature 99.2. Mrs. Roberts denies pain at this time although she appears anxious and very pale. Her medical history includes lung cancer that was diagnosed two weeks ago, peptic ulcer disease with reflux esophagitis, and "fluid retention".
