How does humoral regulation occur in the human body?

Humoral regulation is the control of the work of all organs by means of special substances – hormones. The pinnacle of this regulation is the hypothalamus. It is a part of the brain that produces hormone regulators such as thyroliberin. This hormone enters the bloodstream and from there into the thyroid gland. She perceives the action of thyroliberin as a stimulant and begins to actively create and release its hormonal substances into the blood. They are called thyroxine, triiodothyronine. These hormones are responsible for the metabolism, namely, they stimulate it. The heart begins to beat faster, breathing more frequent, more active sweating. The regulation also happens in the opposite way – when the hypothalamus “recognizes” that there are many thyroid hormones in the blood and reduces the formation of thyroliberin. Similarly, all other organs are regulated by other hormones.
