When the concentration of H⁺ increases above normal, what is the compensating response
A)decreased excretion of H⁺ in the urine
B)increased concentration of H⁺ in the plasma
C)increased reabsorption of all filtered bicarbonate ions
D)increased secretion of aldosterone from the posterior pituitary

Question

Quizplus · Accepted Answer

When the concentration of H⁺ increases above normal, there is a compensating response to increase the reabsorption of all filtered bicarbonate ions. This helps to buffer the excess H⁺ ions and maintain pH balance in the body. Options A and D are incorrect as decreased excretion of H⁺ in the urine and increased secretion of aldosterone do not directly contribute to pH regulation. Option B is incorrect as an increased concentration of H⁺ in the plasma would only exacerbate the acidosis.
