Packet 10 - Fluid Balance (4)

Question 1

Temporary Means of Acid-Base Balance

________, the bicarb ions take up the hydrogen ions released by the acid and become carbonic acid → converted to carbon dioxide and water → carbon dioxide excreted by lungs.

a. ) if too much acid is present
b. ) if blood is too alkaline

Answer 1

Bicarbonate Buffer System

CO₂ + H₂O ⇔ H₂CO₃ ⇔ H⁺ + HCO₃^-

if too much acid is present, the bicarb ions take up the hydrogen ions released by the acid and become carbonic acid → converted to carbon dioxide and water → carbon dioxide excreted by lungs.

Question 2

Temporary Means of Acid-Base Balance

________, carbonic acid will dissociate to release hydrogen ions and bicarbonate.

a. ) if too much acid is present
b. ) if blood is too alkaline

Answer 2

Bicarbonate Buffer System

CO₂ + H₂O ⇔ H₂CO₃ ⇔ H⁺ + HCO₃^-

if blood is too alkaline, carbonic acid will dissociate to release hydrogen ions and bicarbonate.
