Does the medulla monitor blood pH or is it only the receptors in the heart (aorta / carotid bodies)?
no its a me being confused questionIs this a homework question?
It does so indirectly by monitoring CO2 levels. CO2 crosses the BBB freely, which is converted by carbonic anhydrase to H+. in the CSF.no its a me being confused question
you see I have read several different books / sources and they each imply different things
some books imply it only monitors tissue fluid pH (Cerebospinal fluid) some imply it just acts as a co-ordinator and some imply it monitors blood pH
which one is correct ?
