PH & BUFFERING-RENAL BICARBONATE CONTROL
From NeuroRehab.wiki
SUMMARY
3 methods by which the kidneys increase plasma bicarbonate:
1. Reabsorption of filtered bicarbonate: at the proximal tubule & collecting duct
2. Replacement of filtered phosphate with bicarbonate produced by tubular cells
3. Generation of new bicarbonate by glutamine metabolism within tubular cells
