TRUE or FALSE: you can never give too much O2 to a patient
!| !| !| !| !| !| !| !| !| !| !| !| !|



with COPD - Correct answer ✔FALSE
!| !| !| !| !|




if you do so then they will not be able to properly expel CO2
!| !| !| !| !| !| !| !| !| !| !| !| !|




What three things influence the capacity of the blood to carry
!| !| !| !| !| !| !| !| !| !| !|



O2? - Correct answer ✔1. the amount of dissolved O2 in the
!| !| !| !| !| !| !| !| !| !| !| !|



plasma
2. the amount of hemoglobin
!| !| !| !| !|




3. the ability of the hemoglobin to bind with O2
!| !| !| !| !| !| !| !| !|

, What does the CNS regulate in terms of respiration? - Correct
!| !| !| !| !| !| !| !| !| !| !|



answer ✔rate, depth, and rhythm
!| !| !| !|




What does the cerebral cortex regulate in terms of respiration? -
!| !| !| !| !| !| !| !| !| !| !|



Correct answer ✔voluntary control of respiration
!| !| !| !| !|




What does chemical regulation do in terms of respirations? -
!| !| !| !| !| !| !| !| !| !|



Correct answer ✔maintains appropriate rate and depth based on
!| !| !| !| !| !| !| !| !|



changes in CO2, O2, and hydrogen ion concentrations in the
!| !| !| !| !| !| !| !| !| !|



blood (pH).
!|




Where are chemoreceptors found in the body? - Correct answer
!| !| !| !| !| !| !| !| !| !|
