| 3 basic components of feedback control | Receptor, Control center, and Effector |
| Stimulus produces response which is in opposite direction to the stimulus | Negative feedback |
| Stimulus produces response which is in the same direction as the stimulus | Positive feedback |
| Examples of Negative feedback | Body temperature regulation; sugar level in blood regulation |
| Examples of Positive feedback | Labor contractions; blood clotting |
