1) Describe 3 roles of the bicarbonate ion in the body ( hint:one is not a respiratory function)
2) A person was brought to the emergency room unconscious.Breathing was shallow and irregular. A blood sample showed theblood pH to be 7.18(normal 7.4). A mechanical respirator, whichincreases breathing rate, was inserted and sodium bicarbonate wasadministered intravenously.
a) explain why lowered breath rate lowers the blood pH
b) how does the respirator help return theblood pH to normal?
c) what was the reason for administering thesodium bicarbonate?
