An Increase in Sodium and Chloride Ions in the Peritubular

question 47

Multiple Choice

An increase in sodium and chloride ions in the peritubular fluid affects the descending thin limb in what way?

• A)When the osmotic concentration around the peritubular fluid increases around the descending limb the result is a decreased osmotic outflow of water.
• B)When the osmotic concentration around the peritubular fluid increases around the descending limb the result is secretion of potassium ions.
• C)When the osmotic concentration around the peritubular fluid increases around the descending limb the result is an increased osmotic outflow of water.
• D)When the osmotic concentration around the peritubular fluid increases around the descending limb the result is reabsorption of potassium ions.
• E)When the osmotic concentration around the peritubular fluid increases around the descending limb the result is secretion of hydrogen ions.
