Hi, I am looking for some help on Exercise 7 Activity 6...

5. What happens to PCO2 during rapid breathing? Explain your answer.

Rebreathing

2.What happens to PCO2 during the entire time of the rebreathing activity?

Did the depth of the breathing pattern change during rebreathing? Explain your observations.

Breath Holding

3. What happened to the PCO2 during breath holding?

What happened to the breathing pattern when normal respirations resume?

Thanks!!

Nevermind... I think I might have it... unless someone wants to double check my work....

5. What happens to PCO2 during rapid breathing? Explain your answer. PCO2 levels decrease during rapid breathing because more CO2 was removed from the blood than normal.

Rebreathing

2.What happens to PCO2 during the entire time of the rebreathing activity? It increased because the air that was inhaled had increased amounts of exhaled CO2.

Did the depth of the breathing pattern change during rebreathing? Explain your observations. The depth and rate of respiration increased during rebreathing because increased CO2 in the blood causing stimulating of the respiratory centers in the brain stem.

Breath Holding

3. What happened to the PCO2 during breath holding? PCO2 increased dramatically during breath holding because CO2 cannot be released by cells undergoing cellular respiration.

What happened to the breathing pattern when normal respiration resumes? The rate and depth of breathing increased slightly for a brief period when normal breathing resumed to allow PCO2 rates to decrease to the normal range.
