Which kidney function is most directly involved in correcting metabolic acidosis?
Correct answer: A. Excreting hydrogen ions and conserving bicarbonate
- A. Excreting hydrogen ions and conserving bicarbonate
- B. Excreting bicarbonate and conserving hydrogen ions
- C. Reducing urea formation and retaining phosphate
- D. Increasing glucose secretion and reducing sodium loss
Explanation
The kidneys help correct acidosis by secreting hydrogen ions into tubular fluid and reabsorbing or generating bicarbonate. Excreting bicarbonate would tend to worsen metabolic acidosis rather than correct it.

About Urinary System
The urinary system includes the kidneys, ureters, urinary bladder and urethra, with emphasis on nephron structure and urine formation. It explains glomerular filtration, tubular reabsorption, tubular secretion, water and electrolyte regulation, acid base balance, and the roles of ADH and aldosterone in maintaining homeostasis.
