Explain what are the main reasons for the increase or slowdown in the release of hormones in the body, give examples.

Along with nervous regulation, the vital processes of homeostasis of humans and animals are also controlled by humoral regulation – a complex of interrelationships, the key links of which are hormones and the so-called points of their application (in other words, cellular structures-receptors, which perceive the signal given by the difference in the concentrations of humoral factors) … The main difference between hormones is that they act in very low concentrations and are secreted by the apocrine glands directly into the bloodstream and lymph flow, and not into a separate duct. The action of hormones is realized (in most cases) rather slowly, but it is under the influence of these substances that very important processes occur – growth, breakdown of carbohydrates, regulation of metabolic rate and many others. Transportation of hormones throughout the body can be carried out not only with the blood flow, but also through the lymphatic system.

Basic principles of humoral regulation
The intensity of the release and release of a hormone (any) is carried out on the basis of how deviated from the average value of the norm this or that function in the human body. In other words, the humoral system exists in order to maintain all processes in the corridor of the “gold standard”. This applies to absolutely everything – blood sugar levels, growth rates, metabolic processes and much more. For a better perception of the material, several examples should be given.

The influence of hormones on the life process
With an increase in blood sugar, an intense release of insulin is noted, which stimulates the opening of the tubules of the cell wall and the process of assimilation of sugar by cells. Otherwise, glucagon is released, stimulating glycogen depolymerization;
slowing down the metabolic rate increases the intensity of the synthesis of thyroxine, an iodine-containing hormone that accelerates metabolism;
in turn, with a decrease in the content of thyroxine, its synthesis and release, the supraventricular nucleus of the pituitary gland is activated and the release of thyroid-stimulating hormone is observed, which increases the activity of thyrocytes.
