New cards
chemoreceptors function
increases ventilation when it senses a decrease in PH
2
New cards
arterial co2 crosses blood brain barrier
enters cerebral spinal fluid and reacts with the water
3
New cards
Co2 + water in CSF
H+ is increased →
(H20 + CO2 → H2CO3 + H) →
PH is decreased
4
New cards
chemoreceptors in brain interstitial fluid
sense the decrease in PH
5
New cards
decreased in PH sensed
respiration stimulated → ventilation rate increased → co2 exhaled out of body
6
New cards
blood brain barrier
-co2 can cross but not H+
