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
