Respiratory adaptations · Physiology

Renal compensation for respiratory alkalosis during altitude acclimatization involves:

  1. Increased bicarbonate reabsorption
  2. Increased hydrogen ion secretion
  3. Increased bicarbonate excretion
  4. Decreased urine output
Show answer and explanation

Correct answer: Increased bicarbonate excretion

The kidneys excrete bicarbonate to correct alkalosis. This allows ventilation to remain elevated.
