Question
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 theblood pH b) how does the respirator help return theblood pH to normal? c) what was the reason for administering thesodium bicarbonate? 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.

Bicarbonate is an alkaline, and a vitalcomponent of the pH buffering system ofthe body (maintaining acid-base homeostasis).70%-75% of CO2 in the body is converted intocarbonic acid (H2CO3), which can quickly turninto bicarbonate (HCO3).
With carbonic acid as the central intermediate species, bicarbonate, inconjunction with water, hydrogen ions, andcarbon dioxide forms thisbuffering system which is maintained at the volatileequilibrium[1]required to provide prompt resistance to drastic pH changes in boththe acidic and basic directions. This isespecially important for protecting tissues of thecentral nervous system,where pH changes too far outside of the normal range in eitherdirection could prove disastrous. (See acidosis, oralkalosis.)
Bicarbonate also acts to regulate pH in thesmall intestine. It is released from the pancreas in response tothe hormone secretin to neutralizethe acid chyme entering the duodenum from the stomach.
