What is the principle of self-regulation of the body?

Throughout the life of the body, the principle of self-regulation applies. It consists in the fact that when the relative constancy of the internal environment of the body — the central nervous system homeostasis — changes reflexively, without the participation of consciousness, it includes the mechanisms of nervous and humoral regulation. As a result, the activity of one of the systems is aimed at restoring a constant, for example, body temperature, pressure, heart rate. If this is not enough, the body includes conscious behavioral responses based on conditioned reflexes. So, in hot weather, many animals hide in the shade, in burrows, and enter water bodies.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
