Systems Involved In Maintaining Acid-base Balance.pptx

Systems Involved In Maintaining Acid-Base Balance • Buffering system(H2CO3 , HCO3) • Respiratory system(CO2)

• Renal system (HCO3 )

Buffering System • H2CO3 , HCO3 buffer system – primary ECF buffer • Protein buffer system - primary ICF buffer

• Hemoglobin buffer system • Phosphate buffer system

Respiratory System • Increased CO2 = Low pH (acidosis)

• Low CO2 = High pH (alkalosis)

Renal System • [H+] secretion • Formation of HCO3

• HCO3 reabsorption
