Decreases

After hyperventilating in fresh air, blood carbon dioxide content increases or decreases?

Decreases

Results obtained in step 2 under collection data indicate that a decrease in blood carbon dioxide levels is followed by an increase or a decrease in the rate and depth of respiration?

Increase

Hyperventilation into the paper bag causes the blood carbon dioxide content to decrease or increase?

Increase

Results observed in step 3 under collection of data indicate that an increase in blood carbon dioxide will be followed by a decrease or increase in the rate and depth of respiration?

did

The subject was able to hold their breath longer when they did or did not hyperventilate first (without a paper bag).

CO2

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

Directly

Based on the results obtained in these experiments, you can conclude that the rate and depth of respirations are inversely or directly related to blood carbon dioxide levels?

Increases

Normally when blood carbon dioxide levels increase, rate of respiration increases or decreases?
