Question
Hyperventilation (rapid breathing) occurs in response to respiratory acidosis because hyperventilation:A.increases blood pH by decreasing CO2 concentrations.B.increases blood pH by decreasing HCO3- concentrations.C.decreases blood pH by decreasing CO2 concentrations.D.decreases blood pH by decreasing HCO3- concentrations
Solution
The correct answer is A. Hyperventilation increases blood pH by decreasing CO2 concentrations.
Here's the step-by-step explanation:
-
Respiratory acidosis is a condition that occurs when the lungs can't remove enough of the carbon dioxide (CO2) produced by the body, leading to a decrease in blood pH (making the blood more acidic).
-
Hyperventilation is a response to this condition. When a person hyperventilates, they breathe out more CO2 than usual.
-
The decrease in CO2 concentration in the blood leads to a reaction that reduces the amount of hydrogen ions (which are responsible for acidity) in the blood.
-
This results in an increase in blood pH, making the blood less acidic (or more alkaline).
So, hyperventilation is a compensatory mechanism that the body uses to correct the acid-base imbalance caused by respiratory acidosis.
