What effect do increased CO2 levels or decreased pHhave on ventilation? How does this change in breathingaffect blood pH?
The carbonic acid equilibrium is shown below. Exhalation of CO2 by the lungs causes this equilibrium to shift to the ______, which causes the pH of the blood to _______.
H+ + HCO3- <=> H2CO3 <=> H2O + CO2
a) left; increase
b) left; decrease
c) right; decrease
d) right; increase
Describe what happens with PCO2 levels and pH during hyperventilation. Which acid-base disturbance can this lead to?
