Experiment ResultsPredict Question:Predict Question: What do you think will happen to the pH and PCO2 levels during rebreathing?Your answer : b. pH will decrease and PCO2 will increase.
Stop & Think Questions:Which of the following can cause respiratory acidosis?You correctly answered: c. airway obstruction

Post-lab Quiz ResultsYou scored 100% by answering 4 out of 4 questions correctly.
1. Rebreathing simulatesYou correctly answered: a. hypoventilation and respiratory acidosis.
2. Hypoventilation results in You correctly answered: c. an accumulation of carbon dioxide in the blood.
3. The renal system can compensate for respiratory acidosis byYou correctly answered: b. excreting H+ and retaining bicarbonate ion.
4. Respiratory acidosis can be caused by all of the following exceptYou correctly answered: d. an anxiety attack.

Review Sheet Results1. Describe what happened to the pH and the carbon dioxide levels during rebreathing. How well did the results comparewith your prediction?Your answer:pH decreased and P co2 increased as predicted.
2. Describe some possible causes of respiratory acidosis.Your answer:Lung diseases, obstructed airway.
3. Explain how the renal system would compensate for respiratory acidosis.Your answer:Renal system will excrete hydrogen ion to increase pH.
