Question 7

Which statement below lists the essential components of a feedback loop and describes their function?

Accepted Answer

A)  Sensor detects a regulated variable; set point is the value of the regulated variable; integrator interprets the information and sends it to the appropriate effector; effector alters the regulated variable. 
B)  Sensor detects a regulated variable; integrator interprets the information and sends it to the appropriate effector; effector alters the regulated variable; organ system returns the body back to normal 
C)  Integrator interprets the information; set point is the value of the regulated variable; effector alters the regulated variable. 
D)  Set point detects the regulated variable; integrator interprets the information and sends it to the appropriate effector; effector decides if it will react or not to the signal. 
E)  Set point is the value of the regulated variable; integrator interprets the information and sends it to the appropriate effector; effector alters the regulated variable; set point is the point the variable must always return to.
