In a person with hypothermia (low body temperature), what is the specific role of the effector in
regulating body temperature through a negative feedback loop

• the effector detects the deviation in temperature from the set point

• the effector initiates body responses to generate heat

• the effector acts as a thermoreceptor, sending input signals to the integrator

• the effector sends signals to the sensor to activate swear glands and cool the skin even more
