Question
Secretion of $\mathrm{H}^{+}$ into kidney tubules ___a. makes extracellular fluid less acidicb. makes urine less acidicc. can cause acidosisd. is regulated by aldosterone
Step 1
Step 1: The kidneys play a crucial role in maintaining the body's acid-base balance by excreting hydrogen ions (H+) into the urine and reabsorbing bicarbonate from the urine. Show more…

Kidneys adjust the blood acidity by increasing or decreasing the ________ of hydrogen ions $\left(\mathrm{H}^{+}\right)$. a. filtration b. reabsorption c. secretion d. production
When the pH of the blood is high, which substance is likely to be excreted in larger quantities in the urine? (A) ADH increases water reabsorption in the kidney. (B) $\quad$ Aldosterone indirectly increases water reabsorption in the kidney. (C) $\quad$ ADH acts directly on the proximal convoluted tubule (D) Aldosterone stimulates reabsorption of sodium from the collecting duct.
ADH causes (a) Increased water absorption from DCT and CT (b) Increased GFR by increasing blood pressure (c) Increases reabsorption of electrolyte from distal tubules (d) All of these
