Exercise 10: Acid-Base Balance: Activity 3: Renal Responses to Respiratory Acidosis and Respiratory Alkalosis Lab Report
Pre-lab Quiz Results
You scored 100% by answering 4 out of 4 questions correctly.
The renal system compensates for
You correctly answered: d. both respiratory acidosis and respiratory alkalosis.
Respiratory alkalosis is characterized by
You correctly answered: a. pH greater than 7.45 and PCO2 less than 35 mm Hg.
Respiratory acidosis is characterized by
You correctly answered: c. pH less than 7.35 and PCO2 greater than 45 mm Hg.
The functional unit of the kidney is the
You correctly answered: b. nephron.
Experiment Results
Predict Question:
Predict Question 1: What effect do you think lowering the PCO2 will have on [H+ ] and [HCO3- ] in the urine?
Your answer : d. [H+ ] will decrease and [HCO3- ] will increase.
Predict Question 2: What effect do you think raising the PCO2 will have on [H+ ] and [HCO3- ] in the urine?
Your answer : c. [H+ ] will increase and [HCO3- ] will decrease.
Stop & Think Questions:
The condition you just simulated is
You correctly answered: b. respiratory alkalosis caused by hyperventilation.
Can the renal system fully compensate for acidosis or alkalosis?
You correctly answered: d. No, neither for respiratory alkalosis nor respiratory acidosis.
Experiment Data:
PCO2 Blood pH [H+] in Urine [HCO3-] in Urine
40 7.41 normal normal
30 7.58 decreased elevated
60 7.32 elevated decreased
Post-lab Quiz Results
You scored 100% by answering 4 out of 4 questions correctly.
When adjusting the controls, what happens to the blood pH when you lower the PCO2?
You correctly answered: a. The pH increases.
In uncompensated respiratory alkalosis, the
You correctly answered: b. carbon dioxide levels of the blood are low.
What type of breathing results in acidosis?
You correctly answered: d. hypoventilation and rebreathing
With renal compensation for respiratory acidosis, the pH of the urine
You correctly answered: b. decreased because [H+ ] increased.
Review Sheet Results
Describe what happened to the concentration of ions in the urine when the PCO2 was lowered. How well did the results
compare with your prediction?
Your answer:
H+ decrased and HCO3- increased, as predicted.
What condition was simulated when the PCO2 was lowered?
Your answer:
Alkalosis.
Describe what happened to the concentration of ions in the urine when the PCO2 was raised. How well did the results
compare with your prediction?
Your answer:
H+ incresed and HCO3- decreased, as predicted.
What condition was simulated when the PCO2 was raised?
Your answer:
Acidosis.
