A behavioral physiologist is studying the homeostatic control of blood pH. In a trial, a lizard runs on a treadmill for a set amount of time and the blood pH is measured. The blood pH drops as carbon dioxide is released into the bloodstream. Which component of the homeostatic feedback system is responsible for determining if the blood pH is far enough from normal that a response is necessary?
A) effector
B) sensor
C) integrator
D) assimilator
