Hormone means hormone and belongs to the endocrine system of the body. Endocrine system is a huge body fluid regulation system, which plays a role in maintaining the relative balance of the internal environment under the influence of nerve fibers, body fluid pH and electrolytes.

The endocrine of human body is divided into endocrine glands, endocrine tissues and endocrine organs. Endocrine glands include hypothalamus, pituitary, thyroid, parathyroid gland, gonad, adrenal gland and pancreas. Each gland secretes different hormones, and sometimes one gland secretes two hormones with completely opposite effects.

Extended data:

Hormones do not directly participate in the transformation of substances or energy, but directly or indirectly promote or slow down the original metabolic process in the body. If growth and development is the original metabolic process of human body, the increase of growth hormone or other related hormones can accelerate this process, while the decrease will delay growth and development.

Hormones play an important role in regulating human reproduction, growth, development, various other physiological functions, behavioral changes and adaptation to the internal and external environment. Once the hormone secretion is unbalanced, it will bring diseases.

Hormones only play a unique role in certain tissues or cells (called target tissues or target cells). Every tissue and cell in the human body can be the target tissue or cell of one hormone or another hormone.
