Explanation:
The feeedback system is a physiological system composed of negative and positive feedback. Both have the primary function of maintaining the homeostasis of our organism, that is, maintaining a balance in all factors of our body in relation to the internal and external environment.
It is through negative and positive feedback that our organism is able to keep hormone secretion regulated, controlling body temperature, blood flow and blood pressure, consequently, in addition to promoting harmony between all the systems, organs and tissues of our body.
