Today I'm going to be teaching you about negative feedback and what it does to our bodies.
First if you are outside and it is very hot, you will begin to start sweating and continuously sweating until your body is back to a stable state.
The receptors are temperature controlled cells in the skin and brain that receive a signal that the body is too hot and unstable. So, the afferent neurons carry the impulse to the brain to acknowledge the change.
Then the control center which is the thermoregulatory in the brain receives the signal of being unstable and then sends a signal to the effector.
The effector is what fixes the body to be stable again. So when the body is hot the effector will get the body to sweat to release heat.
Once the body is in a stable homeostasis again, the body will stop sweating. So, negative feedback is when the variables like heat have a counter response where everything comes back to normal.
