Chemoreceptors

Chemoreceptors

To the tune of “Breathin” by Ariana Grande

[Verse 1]
All types
Of vertebrates
Have O2 chemoreceptors
That sense the arterial blood
They are
Located
On the carotid artery
In the mammal carotid body 

[Pre-Chorus]
Arterial O2
Chemoreceptors
Generally, increase ventilation
In response to a
Decrease in the
O2 partial pressure
Of arterial blood

[Chorus]
Control of breathin’, and breathin’, and breathin’, and breathin’
Mediated by chemoreceptors
Control of breathin’, and breathin’ and breathin’ and breathin’
Stimulates afferent sensors 

[Verse 2]
Central
And peripheral
Chemoreceptors can detect
CO2 and pH effects
They relate
By carbonic anhydrase
Chemoreceptors in the brain
Can sense the CSF pH

 [Pre-Chorus]
Carbon dioxide
It can flux inside
Across the blood-brain barrier
But protons cannot
So arterial blood
CO2 can be sensed
But not the pH  

[Chorus] x2
Control of breathin’, and breathin’, and breathin’, and breathin’
Mediated by chemoreceptors
Control of breathin’, and breathin’ and breathin’ and breathin’
Stimulates afferent sensors 

[Outro]
Ventilation effects
Of carbon dioxide
By central receptors
Decreases in pH
Like due to lactate
By peripheral receptors
