After hyperventilating into open air, blood carbon dioxide content

decreases

The results obtained in step 2 of data collection indicate that a decrease in blood carbon dioxide levels will be followed by a ___________ in the rate and depth of respiration.

decrease

Hyperventilating into a paper bag leads to a(n) _______________ in blood carbon dioxide levels.

increase

Results obtained in step 3 of data collection indicate that an increase in blood carbon dioxide levels will be followed by a(n) _______________ in the rate and depth of respiration.

increase

The subject was able to hold their breath longer when they __________ hyperventilate into open air.

did

The explanation for the results observed in the previous answer is that hyperventilation decreases the ____________ content of the blood so that it takes longer for it to accumulate high enough to stimulate respiration.

carbon dioxide

Based on the results observed in these experiments, you can conclude that the rate and depth of respiration is ____________ related to blood carbon dioxide levels.

directly

Typically, an increase in blood carbon dioxide levels will lead to a(n) ____________ in the rate of respiration

increase

Tidal Volume

volume of air moved in or out of the lungs in a normal, resting breath

Expiratory reserve volume

volume of air that can be forcefully exhaled after a normal, quiet exhalation

Vital capacity

maximum volume of air that can be exhaled following maximum inhalation

Inspiratory reserve volume

volume of air that can be forcefully inhaled after a normal, quiet inhalation

Residual volume

volume of air remaining in the lungs after a forceful exhalation
