What are the human systems that provide homeostasis? What structures do these systems form?

Homeostasis is the relative dynamic constancy of the composition and properties of the internal environment and the stability of the basic physiological functions of the human body, animals and plants. Constancy is provided by neurohumoral, hormonal, barrier and excretory mechanisms. For example, the equalization of blood pressure is carried out as follows: a change in blood pressure is perceived by blood vessel receptors, a signal about it is transmitted to the vascular centers, a change in the state of which leads to a change in vascular tone and cardiac activity; at the same time, vascular chemoreceptors, including the neurohumoral regulation system, are irritated, and blood pressure returns to normal.
