endocrine
The chemical regulation by the __________ glands is accomplished by a ____________________.
Feedback mechanism
As the flow chart depicts, Jason is receiving feedback from his speedometer about the current speed of his car. Periodically, Jason will receive feedback on the effects the added gas given to his car has on his speed. As long as the car fails to achieve a speed of 55 MPH, Jason’s speedometer will tell him to add more pressure to his car’s gas pedal.
