Nurb 3050 Acid base Exam Questions With
100% Verified Answers
What are the major acids produced during metabolic functions? - answer✔-Volatile (carbonic
acid and is eliminated as CO2) and Nonvolatile (sulfuric, phosphoric, and other organic acids
that release hydrogen)
What is normal pH? - answer✔7.35-7.45
Why does the human body tend to have a slightly acidic environment? - answer✔It keeps the
line between acidic and alkaline very close so that infections can not thrive and so that body
systems can function properly (if it gets too far below 6.8 or too far above 7.8, blood cells start to
die)
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
