Question
Chapter 27.5, Problem 42AYP
Summary Introduction
To analyze:
The change in the blood pH when blood carbon dioxide goes up and down. Also, the reason for this change is to be determined.
Introduction:
Acid is any substance that increases the concentration of hydrogen ion in the solution, whereas the base is the substance that increases the concentration of hydroxide ions. The pH of the plasma is directly proportional to the concentration of hydrogen ion (H+).

What effect does blood CO2 level have on blood pH?
The carbonic acid equilibrium is shown below. Exhalation of CO2 by the lungs causes this equilibrium to shift to the ______, which causes the pH of the blood to _______.
H+ + HCO3- <=> H2CO3 <=> H2O + CO2
a) left; increase
b) left; decrease
c) right; decrease
d) right; increase
Considering the body’s pH balance is impacted by oxygen intake, why would the pH balance of blood plasma increase with rapid breathing? Conversely, why would the pH balance of blood plasma decrease if a person holds their breath?

- During the treatment for COVID-19, one complication includes an increase of CO2 in the lungs. This buildup of CO2 can result in a serious condition called respiratory acidosis if the level of H+ significantly changes. If the pH drops by 1 unit, what has happened to the H+ concentration?arrow_forwardWhat is it called when blood pH is below what it should be?arrow_forwardWhen a person hyperventilates, what happens to his or her blood pH? A person who is hyperventilating is often told to breathe into a paper bag. Why might this help to correct the pH imbalance?arrow_forward
- What effect would drinking a large glass of water have on the salt concentration of your blood? How would the level of ADH change in your blood?arrow_forwardWhen travelling high altitude, one of the problem is alkalosis of the blood. Remember the equation for acid balance: CO2 + H2O ⇌ H2CO3 ⇌ HCO3− + H+ If there is a low amount of CO2 outside, then greater CO2 than normal will diffuse out of the lungs. This will cause the blood to become more basic. To counteract the problem, a drug may be taken to both lower the blood pressure and help correct the pH. To do this, it blocks a symporter of HCO3- and Na+ in the proximal tubule of the kidney. Q: How would blocking transport of HCO3- help to lower the pH of the blood?arrow_forwardWhat is the relationship between CO2 and pH in the blood? Explain.arrow_forward
