The kidneys respond to increased acidity of body fluids by:
A)excreting hydrogen ions
B)excreting sodium ions
C)retaining hydrogen ions
D)excreting potassium ions

Question

Quizplus · Accepted Answer

When there is an increase in acidity (decrease in pH) in body fluids, the kidneys respond by excreting hydrogen ions (H+) to help adjust the pH balance back to normal. This is done through the process of acidification of the urine and excretion of excess H+ ions. This helps to reduce the acidity of the body fluids and restore their proper pH balance. The other options, such as excreting sodium or potassium ions or retaining hydrogen ions, are not the correct responses to increased acidity.
