Q

3 basic components of a Feedback System:

A
  1. )receptor - body structure that monitors any change and sends input to a control center
  2. ) control center- the brain. Evaluates input and sends output for responses. The Efferent Pathway-output flowing from the control center.
  3. )Effector- body structure that receives output from control center and generates response to change the condition

Q

System that reverses a change in a controlled condition.

Ex: BP rising, receptors send signal to brain(control center), thus sending output to the heart and blood vessels (effectors). Heart rate decreases and blood vessels dilate which causes the response to decrease BP.

A
