What are the major buffering agents in the body? - answer✔-Carbonic acid-Bicarbonate Buffer:
operates in lung and kidney; lungs are second line because they can expelled the amount of
carbonic acid by blowing off carbon dioxide and leaving water; kidneys are the third line
because they can reabsorb bicarbonate or regenerate bicarbonate from carbon dioxide and water
-Protein buffering: Intracellular buffering agent; hemoglobin binds to hydrogen ion and carbon
dioxide, becomes a weak acid; hemoglobin not saturated with oxygen is a better buffer
