melomori [17]

Answer:

Attaching letters to the options to make the question readable:

A. If metabolic alkalosis exists, the kidneys slow their acid excretion.

B. If metabolic alkalosis exists, the kidneys slow their acid retention.

C.  If metabolic acidosis exists, the kidneys slow their acid excretion.

D. If metabolic acidosis exists, the kidneys increase their acid retention

The correct answer to the question above is option A (If metabolic alkalosis exists, the kidneys slow their acid excretion.)

Explanation:

Metabolic acidosis is a condition where there is an alteration in the acid-base balance in the blood. Here, as the name implies, a high level of acid than necessary are found in the blood as a product of metabolism caused by an increase in acid production, failure of acid to be expelled in the kidney.  

Metabolic alkalosis is a condition where there is high level of alkaline in the blood than the body requires. Metabolic alkalosis occurs when the kidney is unable to excrete excessive alkaline in the blood and when there is too few acid-producing hydrogen ions present.

Kidneys fight metabolic acidosis by balancing acid levels in the blood by removing excessive acid in the blood through urine. It is also possible for the body to expel volatile acids through the lungs in the form of exhaled air.

Ways kidneys work to neutralize metabolic acidosis, ls If metabolic acidosis exists, the kidneys increase their acid excretion.

Ways kidneys work to neutralize metabolic alkalosis, is If metabolic alkalosis exists, the kidneys slow their acid excretion and increase their alkaline excretion or slow their alkaline retention.
