SOLVED: Acid/Base Homeostasis: How does the body maintain a stable pH?Model 1: Chemical Buffering SystemsA buffer is a compound that resists a shift in pH. When pH is falling (becoming more acidic), the buffer tends to take up H ions. When pH is rising (becoming more basic), the buffer tends to donate H ions to the solution.Bicarbonate buffer system:HCO3- > H HCO3-H2CO3 > H HCO3-Phosphate buffering system:H2PO4- > H HPO42-H HPO42- > H2PO4-Protein Buffering System:R-NH2 H R-NH3
