apnea
no breathing
After hyperventilating in fresh air, blood carbon dioxide content increases? decreases?
⇩ CO2
decrease in blood carbon dioxide levels is followed by an increase? a decrease? in the rate and depth of respiration.
⇩ Rate of Respiration
Hyperventilation into the paper bag causes the blood carbon dioxide content to decrease? increase?
⇧ CO2
an increase in blood carbon dioxide will be followed by a decrease? increase? in the rate and depth of respiration.
⇧ Rate of Respiration
The subject was able to hold their breath longer when they did? did not? hyperventilate first (without a paper bag)
Hold longer
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.
CO2
Based on the results obtained in these experiments, you can conclude that the rate and depth of respirations are inversely? directly? related to blood carbon dioxide levels.
Directly
Normally when blood carbon dioxide levels increase, rate of respiration increases? decreases?
