प्रश्न
Which segment is the site of secretion and regulated reabsorption of ions and pH homeostasis?
Advertisements
उत्तर
- Distal tubule
- Collecting duct
- In the renal tubules H+ and NH4 are secreted and liberated into the tubules and excreted through
urine thus maintaining acid-base balance. - For each H+ ions from the liberated filtrate one Na+ is reabsorbed in the tubules.
- The secreted HCO3, PO3 and NH3 combines to form carbonic acid and phosphoric acids.
- Thus the H+ are maintained and their reabsorption is prevented.
