Question

A 22year old female college student is stressed out due to final exams begin to hyperventilator.This means she is inhaling too much carbonmonoxide .As a result the ph of the blood will become too basic creating Homeostasis imbalance. Her friend hands her a person and instruct her to inhale and exhale into a bag .Breathing in the bag helps to replace the lost Carbondioxide lowering the PH back to normal level.which buffer system in the body will be involved in the reaction

Answer 1

which buffer system in the body will be involved in the reaction

carbonic acid bicarbonate buffer system is the involved in the maintenance of blood pH through hypoventilation and hyperventilation.Hyperventilation results in expelling the CO2 from the blood and reducing the acidic nature .Retaining the CO2 by hypoventilation to keep the acidic nature of blood.

2 H2O + CO2 H2CO3 + H2O H3O+ + HCO3-
  

In the given case of hyperventilation patient was on  respiratory alkalosis state due to the CO2 washout and once the rebreathing via bag made the excess CO2 available in inspiration .It made the availability of carbonic acid in the blood and thus turns into normal PH.

2 H2O + CO2 H2CO3 + H2O H3O+ + HCO3-
