Respiratory Regulation of Acid Base Balance

  • Rapid changes in ventilation cause changes in pH due to shifting CO2 concentrations.
  • When alveolar ventilation changes, the partial pressure of CO2 in the arteries changes.
  • Since CO2 is lipid soluble, it can easily cross the lipid bilayer and Cross the membranes.
  • The change in arterial pH is picked by central & peripheral chemo receptors in the arteries.
  • This information is sent to the respiratory centers in the medulla.
  • Nerve signals are sent to the respiratory muscles to respond
