Homeostasis
When blood sodium ion concentration moves close to the lower limit of normal (137 mmol/L), what would the body do to maintain homeostasis?
More aldosterone would be released to cause more reabsorption of Na+ from the filtrate.
Additional aquaporins would be inserted in the nephron tubule to allow more water to pass into the filtrate.
More aldosterone would be released to cause more reabsorption of K+ from the filtrate.
Water would move into the intracellular compartment to increase the osmotic concentration of blood.
More aldosterone would be released to cause more reabsorption of Na+ from the filtrate.
Homeostasis almost always results in a response that opposes the detected change. Aldosterone promotes the reabsorption of Na+ from the filtrate; this would slow the decline in the blood’s sodium concentration. The other three choices are wrong.
