When the pH of the extracellular fluid declines:

1 the kidneys excrete more sodium ions.
2 the kidneys excrete more bicarbonate ions.
3 the kidneys reabsorb more potassium ions.
4 the kidneys reabsorb less water.
5 the pH of the urine increases.

  1. The kidneys would increase the levels of bicarbonate ion to rise the pH of the blood.

  2. The functional part of the kidney, the nephron is we're excretion and absorption takes place to concentrate urine. If the OUTSIDE environment of the nephron experiences a drop in pH, the neuron has to adjust to make the outside environment more pliable in order to continue excretion and absorption of water and NaCl. Excretion of bicarbonate is the only answer choice that could readjust the pH of the outside environment of the nephron.

    I'm so confused please help when the kidneys secrete hydrogen ions, does the pH of the urine drop? and when the kidneys secrete hydrogen ions, it lowers the pH of the blood also? I really appreciate any help you can give Thank you

    When the kidneys secrete hydrogen ions, does the pH of the urine drop or is carbonic acid formed in the blood? Secondly, when the kidneys secrete hydrogen ions, it would raise the pH of the blood, correct? I'm really confused
