In the presence of both ADH and aldosterone, why did the urinary potassium concentration increase? There was less NaCl reabsorption in the distal tubule and less potassium secretion in the collecting duct. More water was being secreted into the collecting duct. There was more potassium secretion into the distal tubule and more water reabsorption in the collecting duct. More potassium was being reabsorbed in the distal tubule.

In response to increased levels of aldosterone, the kidneys produce a larger volume of urine, urine with a lower specific gravity, urine with a lower concentration of sodium ions, and urine with a lower concentration of potassium ions.

When ADH is present, what is the effect of increasing the medullary concentration gradient on the urine volume? - Urine volume increases and becomes more concentrated. What is part of the filtrate in the nephron; however, would be absent or in low quantities in the urine? - Glucose - Nitrogenous waste - Red blood cells Which hormone would help increase Na+ and water reabsorption and also increases K+ secretion? - Aldosterone
