to the sino atrial node
blood pH is lowered
SA node increases heart rate
more carbon dioxide is produced
this is detected by chemoreceptors in carotid arteries
cardioacceleratory centre in medulla increases frequency of impulses
leads to increased respiration in tissues
impulses sent to medulla oblongata
via sympathetic nervous system

increased blood flow removes carbon dioxide faster, blood carbon dioxide level returns to normal
