pH Negative Feedback System

Hey guys, does anyone know what a specific negative feedback response for an alteration in blood pH levels would be?
And also,  how would you go about explaining changes in the external and internal temperatures of humans during exercise?
Thanks

sensors in aorta and carotid arteries detect a drop in pH and send a message to the medulla oblongata.  It sends a message to the diaphragm to speed up.  The phrenic nerve is the effector neuron in this case.

result deeper, faster breathing.   When pH returns to optimum the signals become less frequent.

Bear in mind that's not the only possible response to acidosis, since it depends on what caused the pH drop in the first place
